Xbox game pass PC - some games not launching

Hi, I have had game pass on PC for a few years now, but in the last couple of months I've noticed that some games will not launch when I press play. I've tried solutions from other similar posts such as:

"Try to open RegEdit as an administrator and delete the following Services:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\GamingServices]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\GamingServicesNet]

Then,restart your computer.

If the issue persists, go to your computer's settings, go to Applications>Applications and Features>Search for the Gaming Services program, left-click on it and then tap on Advanced options and then click on repair."

But this did not solve the issue for me.

Some games will launch fine (ex. Dishonored, Guardians of the Galaxy), but some games will not (ex. TUNIC, Chinatown Detective Agency, Yakuza). While they won't launch, I can see a process in task manager with the game's name and taking up moderate CPU and disk usage.

Please let me know what else I can try. Thanks!
