Hello @A00-r10T, we're using one issue report per unofficially supported game title, and usually I'd transfer this issue report to #8543, however, there's literally nothing usable here for a Proton dev to ponder beyond a one line summary of your experience. Closing as a duplicate.

    In my case the crash does occur even with `trace` enabled, just not immediately as it does otherwise. Not really sure any of this is significant but here are debug outputs. When I have time I dig deeper. 1st Error: [code...
