As long as you never changed your password.
Just get on your account not signed in. like it asks for the password just click the middle button.
If you can do that and stay signed in OFFLINE. Then go to system, storage, all, profiles, the one your locked out of, then switch it to a USB. then it says you have been signed out a few seconds later you should be signed back in. Unless they fixed that.
I have an alternate Email, Recovery code,
And a phone number to recover but this is to help you.
