Compatibility Report

  • Name of the game with compatibility issues: Assetto Corsa
  • Steam AppID of the game: 244210

System Information

I confirm:

  • [x] that I haven't found an existing compatibility report for this game.
  • [x] that I have checked whether there are updates for my system available.

Symptoms

Assetto Corsa wont launch / is stuck in a "running state" without actually running

I've tried a lot of other guides that install dotnet packages manually, or via a script. However none of these get me further. I reinstalled assetto corsa after each try and deletet the prefix folder.
At this point I dont see where my mistake is. I believe that something more systemwide is broken since deleting everything should resolve every thing that i broke during my testing. But it doesnt

Other people said that some update broke my dotnet packages. But steam reinstalls them every time i delete the folder, right? So there couldnt be anything broken left.

Reproduction

Install Assetto Corsa
Try launching it with Proton GE 9-2 / Doesnt launch with any other proton version either
