Symptoms

SnowRunner crashes using the latest proton. The game starts and when the SnowRunner logo appears it crashes. Crash Dump Sending Utility appears. Using older versions of proton the game works fine (i.e. cachyos-11.0-20260520 and Proton Experimental).

Steps to reproduce

1. Launch game using proton-cachyos-11.0-20260521
2. Wait for SnowRunner logo to appear
3. Game will crash
