The error you are receiving is often displayed when Windows isn't able to correctly load the user profile you are trying to log in. It happens because the user profile is damaged, corrupted and there's another issue with it (like part of it is located on a bad sector and Windows cannot access it). There's a Microsoft Support article for that specific error message that also proposes you solution:
By experience, the best solution to fix that issue fast and without playing in the Registry is to back up the user data of the corrupted users, delete their user profile and user and then re-create them. Once done you simply move back the data you backed up in the new profile and you're done.
Let me know how it goes for you
