All I want is an ideally full log with `PROTON_LOG=1`. You should be able to zip it and just attach it here. Steam Deck working doesn't mean much on its own, different settings compared to what people use on a higher-end desktop machine and there's a lot of games that have Deck-specific workarounds.
