If you have old Mods and CC in your Mods folder they may need updates. Especially your Mods. MCCC just updated yesterday and you can download it on their Paetron site for free: https://www.patreon.com/mccc_deaderpool if you have UI cheats or More Columns in CAS those need to be updated too. I am only hitting on the big three, anything else you need to investigate yourself.
For old CC, you should probably run them through the Sims 4 Studio batch fixes. It's best to remove any default replacements prior to running the fixes.
