(PC) Games not launching through gamepass app (PC)

Your Antivirus might be interfering with theStore, try disabling it 'temporarily' to see if it launches. Check Windows Update and install the latest updates.
Sometimes Microsoft releases infrastructure fixes for theStore through Windows Update.

i only use windows defender, but i disabled everything and tried it, even restarted the pc and tried, and still the same thing happens.

just went through a half-day updating process, not sure what took so long there.

Astroneer works as intended, however it seems Ark still does not. I know it's not a hardware issue on my end because I've played the game before on this PC, just this morning I had it working with the Epic launcher (different version)

If you have gamepass installed on your pc try launching the game through that

No, They are not. I had GamePass PC earlier and everything used to work properly but then one day I got notification that there is an offer on GamePass Ultimate so I upgraded but since the day GamePass PC subscription ended and GamePass Ultimate subscription started, I can only launch games that are on EA Play and that too from EA Desktop App only.

Now, because the GamePass Ultimate was a 3 month subscription, so I can't even go back to GamePass PC until it's over.

Any game that launches from Xbox app for Windows fails to launch and tried repairing and resetting the Xbox and Microsoft Apps, sign-out and then again sign-in on both the apps but still same thing.

For Example, Forza Horizon 4 used to work earlier but now it does not.
