You mentioned that you are using a CC mod manager and later on you mentioned Curseforge. As I understand it, those are external programs, but I don't know for sure since I have never used a mod manager or Curseforge. What CC mod manager were you using and is it still installed on your computer? And do you have both your original mods manager and Curseforge installed at the same time?
And how are your mods and cc organized within your mods folder? Are they kept in subfolders or are they just all together in the mods folder and not organized in folders? Edit: It would be helpful if you added a screenshot of your mods folder that shows how you are organized and shows the path to your mods folder at the top.
The reason I ask is because there was a problem with one of the popular mod managers reported last October. I do not know if it has been fixed yet but what happened was that it would cause the game to not see any mods or CC installed in subfolders that were not installed by the manager. What I am thinking is that if you still have the earlier mod manager you were using still installed, that might be the problem. So, if you do, you can try uninstalling whatever it is to see if that clears up your problem. Or you might want to try updating it to see if that will fix the problem. This is a guess since you said that none of your mods or CC was showing up.
Another thing that has been causing mods and CC to disappear and or not show up in the game is the syncing of cloud drives. So, if you have Onedrive or iCloud active, you might want to exclude your Sims 4 user folder from syncing with the cloud. Then make sure that your mods and CC are located on your computer rather than in the cloud.
Hope this helps.
