You need to verify the tenant ID in question. It’s possible that a separate Entra ID tenant associated with your account has remained inactive. This can happen, if for example, you previously set up a trial or free-tier Azure subscription that hasn’t been used recently.
See similar thread with detailed explanation:
So in my opinion since you have been active, most likely it is a different tenant from your main one. You can check by comparing tenant ids
You can mark it 'Accept Answer' and 'Upvote' if this helped you
