Symptoms

I have tested it with Proton 6.x.x and Proton Experimental and after a while of game play the game will crash tho wierdly enough all tho it says it's using Proton Experimental if you force it than from one testing for a session it didn't crash.

Reproduction

Run the game using either Proton 6.x.x or Experimental as your global steam play versions and leave the game not forcing a specific version. I did also test Proton-GE 6.19-2 and had the same issue.
