Hello T0AZTS,
Welcome to Microsoft Q&A forum.
If you can sign in normally with your account. There might be a chance that your account local configuration is having a problem.
Before we proceed further, may I know if the issue persists on other Microsoft apps and the Microsoft website? In the meantime, we can try to clear the credentials cache of the account:
- Log out of your account on all apps.
- Go to Settings > Account
- Select "Sign in with a local account instead" and follow the prompt to switch to a local user. (Only necessary if you're using the affected account to log in to Windows)
- Log in with that local user and go to Settings > Account > My account and remove the affected account from the list.
- Type "Credentials Manager" in the search bar and press Enter.
- Go to "Windows Credentials" and remove all entries related to the affected account.
- Restart your computer and try sign in again. (You can also switch back to Microsoft Account in the user profile.
