Hi,

An interruption with the Xbox Live server, authentication failure of the account's login credentials, and an outdated version of the Xbox app are possible factors as to why you're encountering this issue.

To determine if there's an issue with your Xbox account, kindly sign in to Xbox.com. If you can sign in, that means your profile is all good. Otherwise, follow the on-screen prompts to update your
account information.

Upon verifying that there's no issue with your account, proceed with the troubleshooting solutions below:

Solution 1: Run apps troubleshooter

Running the Windows apps troubleshooter can help resolve issues with apps downloaded from the Windows
