Sims 4 crashing when quitting CAS

I started having this issue after 09/18/2024 update, where basically my game crashes every single time I try and quit Create A Sim. I immediately moved my Mods thinking it would be an issue to do with CC in my game. And I was right, without Mods and CC in my game, my game doesn't crash. However, on an attempt at installing brand new CC, my game continues to crash after exiting CAS. I don't know what to do! I don't understand why CC created AFTER the update can be crashing my game. Anyone have any tips?
