I did everything you suggested. I even took hours adding my mods and cc back one at a time and nothing. I used sims 4 mod manager to disable everything. nothing. I repaired the actual game. nothing. I have spent days trying to fix this and am getting no where. am I just going to have to face the Music and delete everything and start from scratch? or is there anything else I can do to fix this problem.
I also want to add that it wasn't a default replacement issue you had mentioned because I don't use them. I just never really see the need. all I use are recolor options that go along with the original mesh or just use the games product
Sims 4 Mod Manager could actually be part of your problem. It likes to rename files, making it very easy to end up with installation problems and duplicates. I strongly advise against using it.
If you can open Sims when there's nothing in the Mods folder then the issue is something in there. The timing could be coincidence with the changes you made, so it might not be related to the CC you changed. I'd suggest redownloading as much of the content you use as possible from Curseforge or modders' own sites but manage it yourself. Check against Broken/Updated Mods for a selection of mods to not redownload. For the CC, start with the backup files that S4S made.
