[2020] On gamepass, crashes straight after pressing play on launcher

You are definitely running the game from the Xbox app, not the MS Store app? And the MS Gaming Services app is updated?  

Yes.

I don't suppose the 1.1.3 patch helped?  

Is the MS gaming services app 2.46.7001.0 ? If anything earlier it needs an update too.  

I missed this before:

[13:11:36][virtualfilesystem_physfs.cpp:1549]: Could not open file: pdx_settings.txt, error: pdx_settings.txt permission denied
[13:11:36][pdx_settings.cpp:571]: Could not write settings: Could not open file: pdx_settings.txt

What antivirus app do you use?
