This can be caused by a many different things here's a list of things to try:

• Install Microsoft Visual C++ Redistributable 2019.
• Reboot your computer, maybe another process is trying to read the database file.
• Disable antivirus software, Avast and AVG are known to delete Cef/VRCX.
• Remove AVerMedia AssistCentral this is known to cause problems with VRCX for some unknown reason.
• Unstable RAM can be a potential cause, remove any RAM overclock and run MemTest86.
• Run VRCX as administrator, this can fix it on some rare occasions.
• Test a fresh database, first close VRCX then backup your current database by opening %AppData%\VRCX\ and renaming VRCX.sqlite3 to something like Backup.sqlite3, if this solves it but you'd like to still keep your data follow the steps bellow on how to repair your database.

• Try launch VRCX with the launch parameter --gpufix.
• Disable SteamVR safe mode.

• Installing Wine

  • Arch Linux: Wine can be installed by enabling the multilib repository and running sudo pacman -S wine

  • Ubuntu: Please refer to the wiki

• Winetricks Magic

  It is imperative that you are using Wine 7.0rc5 or later! this has not been tested on earlier versions. Wine 7.0 Finally allows for full installation of the .net framework, which is needed for VRCX to function.

  • Start over with a clean wine prefix. Either create one for VRCX or rm -rf ~/.wine and use the main prefix.

  • winetricks --force dotnet472 yes, you'll have to sit through all of the installers (there's a lot of them).

  • winetricks corefonts

  • winetricks winecfg

  • Set it to Windows 10 for good measure, you should just be able to run wine VRCX.exe now. Should you get an error about CEFSharp, you can try wine VRCX.exe -no-cef-sandbox

• Notes

  • VRCX on Linux is known to have a nasty memory leak so keep an eye on memory usage or restart it frequently.

  • If you have a laptop that uses hardware muxing with an Intel iGPU you'll need to set your graphics device in nvidia-settings to only the NVIDIA GPU.
