Automatically logging onto an unloadable kiosk account without being able to log onto the admin account

[jerryemy]

I curiously made an assigned access kiosk account with Edge as its app. After I logged out and tried logging onto the kiosk account, it said that the user profile service (and in other tries it said ProfSvc) failed and I cannot use the account at all. After I logged out, I saw that my admin account is hidden and I cannot log onto it at all. However, I can still log onto it in Recovery Environment. But I don't know what should I do in RE and I don't want to reset my PC, so please anyone give me any advice and ask me any progress. I'm OK with system changes and I have an usb installation media if it's ever needed.
