Custom Content not showing up in The Sims 4

hello, I seem to be having a problem with my mods. I was playing sims on Monday and Tuesday perfectly fine up until I had to update my game. After the update, my game became very slow. none of my CC appeared in CAS, even when my mods/script options were enabled. I then removed the mods but the game was still running slow. I tried repairing the game through Origin but that didn't work either, and all of a sudden my game would not launch without freezing at the sims 4 logo, so I uninstalled it. I reinstalled it again the next day and it was running fine without my mods. today, I have just added the mods into the folder again, but it has frozen on the sims 4 logo while launching. I then removed them from the folder straight after, and game is running with no problems... hmm. prior to the update, everything was running smoothly. I have about 60 cc. any advice?
