Hello @pbaesse, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/725#issuecomment-860037952.
As a side note, "Proton Version: Default" means absolutely nothing. There is no default version of Proton for non-whitelisted game. At some point you manually chose a version to run other titles with use in Steam's settings.
