Managing personal Outlook.com account settings, security, and privacy
Hello,
Since you've still logged in to your @hotmail.com Account on your local computer, your account may not be deleted due to inactivity.
So, your account might have been compromised.
When you look up your username using the recovery email address or Phone number, do you see your @hotmail.com address in the list?
https://account.live.com/username/recover
If you do not see this email address in the list and you see a different address there, your account might have been compromised. So, in this situation, you cannot use the standard recovery form to regain access to your account. Instead, you have to submit the Account Recovery request directly through the Xbox recovery team.

I think you have submitted the same.
Now wait for a reply from the Microsoft recovery team. If you no longer receive emails, check your junk or spam email folder, or add the @microsoft.com address to your safe senders list.
