Okay so after some trial and error i managed to fix achievements in my case (i used /editor) and with the help of AI (yes I don't know much Python) I made a script that, at least in my case, worked. Would appreciate if someone else tried it and told me if it worked, thanks!

to use it: python ...

Sup, ran /editor in my save and wonder if there's any known bay to re-enable achievements. Tried the python script with no luck. Thanks!
