New laptop. Sign-in not possible?

I bought a new laptop and followed the instructions. Then I was registered and everything was fine. However, I did not want to log in with a PIN every time and tried to delete it, but something went wrong and I can no longer log in when I log in again. He still wants a PIN, but if I enter my chosen PIN, he won't accept it. I could have one or something sent to me via telephone number, but I have given this incorrectly. How do I get back in? I would very much like to restore the whole thing from scratch and log on again from the beginning, so to speak, system recovery.

Who knows or who can tell me what I can do?

A heartfelt thank you
