End G Hub Process via Task Manager

Once opened, go to the Processes tab, and right-click on every task related to G Hub. Now, select End Process. After you are done with this, launch the application to check if it works.
Download an older version

All you need to do is head over here (third-party webpage) and download one of the older versions of the applications. Once downloaded, install it and then check whether the critical error occurs.
Clean installation
If none of the workarounds were able to help you fix the issue, then it’s time to try the reinstall method. So, start by uninstalling the application from your system. After this, you will need to delete the LGHUB folder from a bunch of directories. These are as follows:
- C:\Program Files
- C:\ProgramData
- C:\Users\<user name>\AppData\Local
- C:\Users\<user name>\AppData\Roaming
Now, open the Registry Editor on your system by typing regedit in the Windows Search box. In the Registry Editor, go to “HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\”, and delete the following key ” {521c89be-637f-4274-a840-baaf7460c2b2}”.
