The correct password in the Pc diagnostic window does not work.

Hello everyone, I have an unpleasant problem. I reset the network settings through settings and after that I can't start my PC. I turn it on and eventually I see that the pc Automatically restores And it includes PC diagnostics. After trying to restore the computer to its original state, the system asks me to enter my password. I enter the correct password, but everything happens unsuccessfully. I changed my password through Microsoft and nothing has changed. Unfortunately, deleting files won't work for me.

The system asks me everywhere (except startup options) to enter my password
