I found a fix, I deactivated an active plugin called Theme Login or something of the sort.
Allowed me to login without any problems

I changed the theme name, however, the same problem is occurring. The forms still don’t show. I just updated WordPress manually a few days ago, do you think that has anything to do with it?
Updating it manually worked, thanks!
