Summary of Issue: Experience crashing on starting game and joining party. Upon launching from steam, game will appear to launch, show deadlock loading symbol for a moment, go black, then freeze. At this time, steam will close. Deadlock process will stay open but be unrecoverable. ~1/6 of boot attempts successfully launch game. When able to load game, freezing and steam application crash occurs upon attempting to join party. Game does not crash at sandbox loading screen.
Troubleshooting steps: attempted to switch between Proton versions 8.0.5, 9.0.4, and experimental. experimental and 8.0.5 produce described behavior, 9.0.4 fails to launch game.
