can I ask why you done that ?..
EDIT: I’am in parallel in clarification for what should these GamingService be necessary ( xcloud ?) .
If you need it, then my guess that possible the firewall block some of the new installed service.
If MSFS worked former fine without it, I find in meanwhile also a link in forum where a users describe howto remove this GameingService : MSFS not working shows "Gaming Services" Microsoft Store? - #7 by TenPatrol
note: I not have these GameingService stuff installed and it is also not directly shown within the MS-Store.
