The following was posted online and worked for me. I thanked and advised the author.
Using Terminal as Administrator.
“get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers”
"Restart your PC, open PowerShell as admin again, and enter" - restart is VERY IMPORTANT
Using Terminal as Administrator after restart.
“start ms-windows-store://pdp/?productid=9MWPM2CQNLHN” - All done.
