Symptoms

Game seems to freeze after some minutes of playing, can move cursor.

Reproduction

Start game, play for a couple minutes, ???, game freezes.

Trying workaround: launch options %command% --cores 1 as per https://www.protondb.com/app/799600
Edit: --cores 1 seems to help so far, no crashes.

No source file or failing test is identified in this compatibility report. Start by reviewing the attached Proton log and reproducing the freeze with Proton 7.0, then compare behavior with the reported --cores 1 workaround; a useful result would require a reliable reproduction and an actionable cause.
