Hi all, I installed GTA 4 Complete Edition from Steam. The first time I tried playing after installation it worked flawlessly but has been giving me this error ever since. I have tried uninstalling and reinstalling and I have tried using a different Proton version only to get the same error again. I am on Linux Mint 21.3 Cinnamon with 13th Gen i7-3700K, RTX3080 Ti and 32 GB RAM. I haven't been able to find any help on Proton DB, hoping somebody here might have some idea. And I apologize if this is no the right place for this post, please let me know where I should post it. Thanks!
Thank you so much. This worked like a charm but now that the error is gone it tries to launch the Rockstar Launcher but crashes without any error messages.
If you go into the game's preferences in steam, you can modify the launch command to enable logging:
PROTON_LOG=1 %command%
Then when you launch the game it should put a log file in your home dir. That will hopefully give a clue as to what the problem is.
