[MOD RELATED] Game not loading with origin

I finally got my save games to load after I disconnected from one drive. Now I'm playing using the C Drive ( Eventually I want to move it to D drive since that has the most space ). At first I had a problem with white boxes appearing in game with the panels for play pause weather. I immediately knew that most likely related to a UI cheats mod or one of my mods. I took my mods out and play tested by itself. Without mods it worked but not with all of them present. During this testing the game would have these pop ups come up with the different packs as if they were not already loaded on the game e.g. Tiny living, Haunted House, and Highschool Pack would pop up. Also I moved a lot of CC to my mods that I've downloaded. Now Origin keeps crashing and states certain packs are not downloaded. Steam would also give me messages like 9 of the downloads are missing. I have found broken mods or outdated mods cc using the 50/50 method. At the point I don't know if I should uninstall and reinstall Origin because now it's having problems. Normally I would just repair if I'm trying to get my game to work. What could be the culprit? I thought it had to do with the space I had in my drive. But it's not entirely just yet.
