I found a solution my problem: "Bokomaster 5 points· 2 days ago Found a solution that will work that requires you uninstalling and reinstalling the Gaming Services through Powershell.
Launch powershell as an administrator and enter “get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers”
In the same powershell window, enter “start ms-windows-store://pdp/?productid=9MWPM2CQNLHN”
Install the app on that page, including accepting the UAC prompt when shown.
Try installing the game again." source: https://www.reddit.com/r/PSO2/comments/grph6n/try_again_later_something_happened_on_our_end/
Thank you!! I managed to download PSO2 again the Microsoft store doing this!
