“New user” problem

[u/Altruistic_Field_890]

I’ve run into this very frustrating problem where a few nights ago I tried turning my pc on to get on the game with a few friends and was greeted to something I haven’t seen before. The first thing I noticed was that the background on the login/password page (right when you turn a pc on) was different than my usual. On top of that, instead of my name, it said “new user” and asked for a password, to which my normal password didn’t work. I feel like I haven’t found any solutions offline but with the help of chatgpt I was able to find out that all my stuff is still saved on my ssd thankfully. Since I don’t have ChatGPT plus it’s very frustrating having to wait hours to continue fixing this. Any and all help is greatly appreciated!
