Yes, this is precisely why you need to have an admin account that’s not restricted to AD authentication and can login locally as well. If you do not have one login to the database, go to the _staff table, find your account, set backend to NULL, and if you don’t have a password you need to set one. Passwords are Bcrypt hashes with 8 round entropy. There are many sites online that can hash it for you.
Cheers.
