Hello @tuxrinku, the log you attached doesn't look like a Proton log, please add PROTON_LOG=1 %command% to the game's launch options and attach the generated $HOME/steam-$APPID.log to this issue report as a file. (Proton logs compress well if needed.)
That said, in the log you shared, fixme:dbghelp:x86_64_fetch_minidump_module RunTime_Function outside IMAGE_DIRECTORY_ENTRY_EXCEPTION unimplemented yet! looks like a possible line of interest.
Sorry, here's the proton log.
steam-851850.log

Symptoms
When launched, a "Fatal Error" window about UE4 (Unreal Engine I assume) appears. When I click Ok the game quits.
