Unable to Sign In to Microsoft Account to Redeem Xbox Game Pass Code

I'm experiencing difficulties signing in to my Microsoft account to redeem an Xbox Game Pass code. Whenever I try to log in, I encounter the message "You signed out of your account. It's a good idea to close all browser windows." I've tried various solutions like changing browsers and using private tabs, but the issue persists.

Has anyone else encountered this problem? If so, how did you manage to resolve it? I'd appreciate any advice or insights on how to successfully sign in and redeem my Xbox Game Pass code.

Thank you in advance for your help!
