err:winediag:CorIsLatestSvc If this function is called, it is likely the result of a broken .NET installation is a line of interest from the log.
If it'd be at all helpful, here's the log after installing .NET 4.7.2 manually in the relevant prefix; the CorIsLatestSvc error doesn't occur anymore, but the behavior is still the same: steam-611800.log
This looks like a Unity game. It doesn't use .NET, but maybe it runs the installer for some reason.
