Xbox App for PC unable to launch certain games

I had tried your suggestion once since it was suggested by other people when googling my issue, but now I have tried it once more and the games still won't launch at all.

Try reinstalling the Gaming Services app on your Windows 10 device:

- Right-click the Start button in the lower-left corner of the main screen, and then select Windows PowerShell (Admin).

- In the Administrator: Windows PowerShell screen, type the following command and press Enter:

get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers

- In the same window, type the following command and press Enter:

start ms-windows-store://pdp/?productid=9MWPM2CQNLHN

- Install the app on that page, and select Yes when you receive the User Account Control (UAC) prompt.

- Restart your device, and try to install the game again.

The error code i get in the event viewer app is 2279672784 along with the message [LaunchProcess].

Sorry you're still having trouble. If you are still unable to launch the game from the Beta App then please find the game in the Start Menu of the PC and launch it from there
