If you’re using Steam then you could try adding PROTON_LOG=1 %command% to your launch options for the game. This will output a log file into $HOME/steam-$APPID.log ($APPID will probably be 823130 in this case). This log file might show why the game isn’t starting. You could even post this log file here as a pastebin link to see if anyone can help diagnose if you’re unable to see anything obvious.
