Alright DEFINITELY do more research then I did cause I probably have caused problems I do not know of yet BUT I found a way that if it DOESN'T cause problems got MINE working again FOR NOW. get ReSaver and go to your save delete all script instances, why I say DO MORE RESEARCH I was dumb and was like "Eh can just load a earlier save file" now that I think about it there is no way I know what is going to happen in the future but WE SHALL SEE. So I do stress ask others on the ReSaver page how dangerous this is and the possible problems that may arise from doing this but it did get my MCM working. Edit: so it bugs some quests so that is a problem with this approach so I will advise checking it out more and I will check around to see what files to delete instead Edit 2: So figured out a way that seems to not bug quests still using resaver. Go to either plugins (full) or (lite) depending if skyui is a lite or full mod for you find "SkyUI_SE.esp" click it so a menu pops up go to "SKI_ConfigManager" in the menu that is there, click it, will bring you to the file (highlighted) on the left and delete the file. save as a NEW Save don't override it just in case you did something wrong. will also advise going to "clean" at the top and clearing unattached instances and unattached elements.
