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!
Appears it should work pretty well according to ProtonDB

You might need to install ProtonUp-QT and grab GE-Proton and set the game compatibility mode to “
Proton ExperimentalGE-Proton”There are also suggestions of downgrading the game version to remove the launcher (Im assuming the launcher does the windows version check)
And this user’s problem/solution sounds identical to yours
