--- Comment #3 from Sven Arvidsson sa@whiz.se --- FWIW, there are no crashes when dxvk is used. This obviously doesn't help Wine, but it is pertinent to Proton and a workaround to enjoy the game.
Also, disabling the d3d11/d3d10 dlls and forcing the game to use the d3d9 renderer still exhibits the hangs. But the backtraces now point to the video plugin used by Unity (avprowindowsmedia).
