Authorisation problem with Xbox application, how to solve it?

Hello,

I'm having a huge problem with my Xbox game pass application.



On my computer, when I install a new game and launch it, the "connection in progress" window loads indefinitely. Specifically for each new game I install.



I've tried to find a solution but nothing works.



However, I found this:



When I install new games on my laptop and launch the game, the application asks my PC for authorisation to launch the game. Authorisation that it used to ask for on my main computer too, but which it doesn't do any more.



So, if I accept the authorisation on my main computer and go back to my other computer to launch the game, it works and the game runs perfectly.



So I'd like to know how to get this authorisation request back. Because I uninstalled the application but it didn't work. I don't know what to do and it's frustrating me enormously.



Thank you for your help.

:)
