Hello Viktor Bojčuk,
Welcome to Microsoft Q&A forum.
It's unfortunate to hear that your account has been hacked and the hacker has started the process of deleting the account.
It's good to hear that at least you have been able to reset the password. However, as you've described, the hacker might have set up 2FA on your account.
