Logitech G Hub critical error is often caused when the app’s components are not running in the background. The application requires the Logitech G Hub agent process in the background for it to work properly. In addition, the error message can also be attributed to certain versions of the app in which case you will have to perform a downgrade.

Logitech G Hub Critical Error - 1

Logitech G Hub Critical Error

In some cases, corrupted or damaged installation files are another reason the error message may arise. In this article, we will take you through a number of methods that you can use to resolve the issue in question.

1. Unplug Logitech Peripherals

The first thing that you should do when starting to troubleshoot the critical error message is to unplug any Logitech peripherals that are connected to your computer. In some cases, the error messages occur when Logitech G Hub is not able to detect your peripherals properly, or a third party is interfering with it.

In such a scenario, one way of fixing the issue would be to force the app to detect the Logitech peripherals again whilst it is running. To do this, unplug all of your Logitech peripherals from your computer and then plug them in again. The application will detect the newly plugged-in peripherals and even perform a restart when you unplug the peripherals.

After the app starts again, the problem should no longer be there. If the problem persists, move to the next method below.

2. Run Logitech G Hub Agent Process

In some scenarios, the issue can occur because the application is not able to communicate with its components. Logitech, like most other programs, uses an agent process to communicate with the Windows operating system and it returns the information to the main app for processing.

In some cases, the agent process does not function properly when you open the Logitech G Hub application, which prevents it from operating as it should. In such a scenario, you will need to manually start the Logitech agent process on your computer. To do this, follow the instructions below:

  1. First, open the File Explorer window. Opening File Explorer
  2. After that, navigate to the Logitech G Hub directory, which is C:\ProgramFiles\LGHUB .
  3. There, locate the lghub_agent.exe file and double-click on it to execute it.
  4. This will start the agent process in the background.
  5. See if that fixes the issue.
  6. If the issue persists, quit the Logitech G Hub app, start the agent process again and then open Logitech G Hub.

3. Download an Older Version

In some instances, the error message you are experiencing can be due to the version of the app on your computer. This is not something new as bugs from the dev team are not entirely uncommon. This can also happen when the version of the app on your computer is not able to function properly with one of the Logitech peripherals you are using.

In such a scenario, you will have to download an older version of the app and install it on your system. This can also be helpful when you have started experiencing the issue after the latest update. If this case is applicable, you will have to disable auto updates so that the application does not update to the latest version again, causing the issue in question.

As it turns out, you cannot download an older version of the app through the official website. However, there are download links available for older versions of the app that work properly. In case the application auto-updates during the installation process, you will have to disconnect your computer from the internet during the installation process and then disable auto updates after the installation has been completed.

To download an older version of the Logitech G Hub application via the official website, click the download link here . See if that resolves the issue.

4. Clean Install Logitech G Hub

The installation files of Logitech G Hub can be another possible cause of the critical error message. This can happen when the installation files are either damaged or corrupted , preventing the app from working properly. In such a scenario, you will have to reinstall the Logitech G Hub on your system.

However, performing a simple reinstall is not always enough. This is because when you uninstall the app, there are remnants left on your computer that are utilized when you install the app again. Therefore, it is important to perform a clean install where you remove every trace of the application from your system before installing it again. To do this, follow the instructions below:

  1. First, open the Control Panel by searching for it in the Start Menu. Opening Control Panel
  2. On the Control Panel window, click on the Uninstall a program option. Navigating to Installed Applications
  3. There, from the list of programs, locate Logitech G Hub and double-click on it to remove it from your computer.
  4. After that, navigate to the following directories and delete the LGHUB folder in each location: C:\Program Files\ C:\ProgramData\ C:\Users<user name>\AppData\Local\ C:\Users<user name>\AppData\Roaming\
  5. Once you do that, open the Run dialog box by pressing Windows key + R on your keyboard.
  6. Type in regedit and hit Enter. Open Windows Registry
  7. This will open the Windows Registry.
  8. Delete the following Windows Registry key: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{521c89be-637f-4274-a840-baaf7460c2b2}
  9. After that, restart your computer.
  10. Finally, reinstall Logitech G Hub and see if the issue persists.

5. Perform a Clean Boot

If all of the methods have not resolved the issue for you, the problem is likely caused by the interference of a third-party application. This happens when a third-party app is interfering with the Logitech G Hub app, or another program on your computer is accessing your Logitech peripherals, preventing the application from direct access.

In such a scenario, you will have to perform a clean boot to see if that resolves the issue. Clean boot starts your computer with only the required Windows services running in the background. Therefore, all of the third-party services are blocked on startup.

If the problem goes away in clean boot, it will be evident that a third-party app was causing the issue. In such a scenario, you can start activating the services one by one to find the culprit. To perform a clean boot, follow the instructions down below:

  1. First, open the Run dialog box by pressing the Windows key + R on your keyboard.
  2. In the Run dialog box, type in msconfig and hit Enter. Opening System Configuration
  3. This will open the System Configuration window.
  4. There, navigate to the Services tab.
  5. Tick the Hide all Microsoft services checkbox. Hiding Microsoft Services
  6. After that, click on the Disable all option and hit Apply. Disabling Third-Party Services
  7. Then, switch to the Startup tab and click the Open Task Manager option. Opening Task Manager
  8. On the Task Manager window, select the apps one by one and click the Disable option. Disabling Third-Party Apps
  9. Once you do that, restart your computer to perform a clean boot.
  10. After your PC boots up, open the application to see if the problem is still there.

How to Fix “Printer is in an error state” Issue?

The error “ WinRAR Error: Next Volume Is Required ” usually appears when you’re extracting a multi-part RAR archive and WinRAR can’t find (or can’t correctly identify) the next file in the sequence . This often happens when a volume is missing , stored in a different folder , or renamed in a way that breaks the archive’s expected order .

Fix: Logitech G HUB Application encountered a critical error - 2

In this guide, we’ll go over the most reliable fixes confirmed by affected users, along with what each method is doing behind the scenes so you can choose the right one for your situation.

Important: To extract multi-volume archives, you should always start extraction from the first file in the set. This is usually file.part1.rar , or (in older sets) the main .rar file that comes before .r01 , .r02 , and so on.

1. Download and Place the Missing RAR File

WinRAR needs all parts of a multi-volume archive to complete extraction. This error usually appears when one of the volumes in a set like .part2.rar , .r01 , .r02 , .001 , and similar naming formats is missing . Downloading the missing volume and placing it in the same folder as the other parts allows WinRAR to continue extracting normally .

  1. Look at the error message or review the list of archive parts in the folder.
  2. Identify which volume is missing (for example, part2.rar , .r02 , .001 , etc.).
  3. Go back to the website or source where you downloaded the archive.
  4. Locate and download the exact missing file using the same naming format as the others.
  5. Make sure the new file name matches the pattern of the rest. Example: If you have file.part1.rar and file.part3.rar , the missing one must be file.part2.rar .
  6. Move the downloaded missing volume into the same folder as the other archive parts.
  7. Confirm that all parts are in a single folder before extracting.
  8. Right-click the first file in the series (usually part1 or the main .rar file) and select Extract Here or Extract to Folder .
  9. WinRAR should now detect all volumes and continue extraction normally .

2. Manually Browse & Select the Next Volume

Use this method only if the next volume already exists , but WinRAR is failing to detect it automatically. This can happen due to incorrect naming , the file being in a different location , or a temporary file access issue. Manually browsing helps WinRAR locate the correct volume and resume extraction without interruption .

  1. Right-click the first file in the series (usually .rar or part1.rar ) and select Extract Here or Extract to Folder .
  2. When WinRAR cannot find the next volume, it will show the “ Next Volume Is Required ” message.
  3. A small window will appear, allowing you to manually select the next volume .
  4. Use the file explorer window to locate the folder where the other archive parts are saved.
  5. Select the next part based on the naming order (example: select file.part2.rar after file.part1.rar ).
  6. Make sure the selected file matches the naming format of the archive (no extra characters like (1) and no mismatched numbering).
  7. WinRAR will resume extraction using the selected volume .
  8. If additional volumes are missing or stored separately, WinRAR may prompt you again. Repeat the same process until extraction completes.

3. Rename the RAR files in Order

WinRAR relies on a proper naming sequence (such as file.part1.rar , file.part2.rar , file.part3.rar ) to extract multi-volume archives. If a file is named incorrectly, contains extra characters, or is out of order, WinRAR may fail to locate the next volume and show this error. Renaming the files correctly helps WinRAR follow the sequence and extract the archive without interruptions .

Note: Renaming only changes the file name , not the file contents. The goal is to restore the correct sequence so WinRAR can detect the next volume.

  1. Go to the folder where all the RAR files are saved.
  2. Make sure all parts of the archive are present and stored in the same folder .
  3. Check how the parts are currently named . Common patterns include:
file.part1.rar, file.part2.rar, file.part3.rar
file.rar, file.r01, file.r02, file.r03
  1. Look for files that don’t match the expected numbering pattern (for example, file.part01.rar , file.part1(1).rar , or unrelated names).
  2. Rename each file so it follows the same order without extra characters or mismatched numbering. Example:
Incorrect: file.part1.rar, file.part3.rar, file.part2(1).rar
Correct: file.part1.rar, file.part2.rar, file.part3.rar
  1. Make sure the text before the number is exactly the same for all files.
  2. Only the last part number should change.
  3. Right-click the first file in the series (usually part1.rar or the main .rar file) and select Extract Here .
  4. WinRAR should now recognize the sequence and continue extraction normally .

If you still get the same prompt: the archive set is likely incomplete (a part was never downloaded or was removed), or one of the volumes is corrupt and must be re-downloaded from the original source.
