I'm sorry to hear that you're experiencing this issue. I'm happy to help.
Based on the error message you are getting, the hacker has already changed your account information, such as your email address, and then deleted it. Please note that if your email account ends in @hotmail, @outlook, @live, or @msn and was removed, replaced, or deleted, it cannot be used to create another account. You will receive an error message stating that it is already in use.
If the account information has already been changed, I'm afraid the account may no longer be recoverable, and the account recovery form may not work as well. You can check the Microsoft article below to see if it can help.
