Symptoms

Game freezing on loading (initializing) screens. It randomly happens only on attempts to load to the Space Rig (lobby).

Reproduction

Select latest CachyOS Proton (even native one), launch the game and try to reload to lobby by disbanding team (ESC -> disband team), or loading other save (ESC - settings -> save menu -> load save), or just finishing mission.

I assume I started having this issue after the linux-firmware update, which required to reinstall it. And this issue doesnt happen with Proton Experimental.

Can reproduce locally, see if it's happening with Proton Experimental.
