Hello @BernhardMayrhofer, err:module:import_dll Library OpenAL32.dll (which is needed by L"Z:\\var\\home\\user\\.local\\share\\Steam\\steamapps\\common\\soul Interface\\int_x64.exe") not found looks like the line of interest from your log.
Upstream wine de-bundled OpenAL a while ago and Proton followed the upstream change. The game dev(s) should provide an OpenAL redist installer as part of the game's first run setup.
Having written that, it might be interesting to test how the game behaves with Proton 7.0-6.
Howdy, I'm unsure if I should be creating a new issue or not, but I figured it's relevant here.
(Essentially a Steam Deck OLED.)
steam-2878890-9.0-3c.log
steam-2878890-7.0-6.log
The game will boot to a black screen and be fully unresponsive until the user manually ends the process.
Hopefully this helps.

I tried 7.0-6 as well, could not start the sim.
