Symptoms

Possible regression(s) in Proton 4.2-7 as it has far more trouble starting the game than 3.16-4. In the best case with Proton 3.16-4, the game runs and plays but then shortly (within 2 minutes or so) closes the game window and continues to stay running in Steam until process is manually ended.

Logs contain far too many fixme's and files not found. Too many errors.

4.2-7 also may need a start from the terminal but complains about missing openvrpaths.vrpath file which creating one (non-empty internet search for contents) may have improved starting of game (but still worse than 3.16-4).

Reproduction

Install and then play

Start by reproducing CrossCode with Proton 3.16-4 and 4.2-7, then compare the two linked logs and investigate the reported openvrpaths.vrpath behavior. Done means identifying the cause of the startup and early-exit problems and confirming whether the behavior is a Proton regression.
