Activate Windows?

So I bought a PC about 1-2 years ago and then a Windows 11 key with it, that worked until one day I reset my PC because I read that you can do it so that the computer runs a bit better again, so I reset it, then after the reset I noticed that my Windows was no longer activated and I had a Windows 11 enterprise version that was not activated on my PC, no matter what I tried, generic keys from the Microsoft website or I bought a Windows 11 home key because I actually had that version and I also bought a Windows 11 enterprise key, but none of that worked and now I don't know what to do because I haven't been able to carry out regular Windows updates for 2 months, error message see image below.

PS: I've also tried the key I bought first, right from the start, and that didn't work either.
