Well, if this happened after downloading cc, then you have to remove those who are broken... I'm sorry, but you can't have broken content in your game and expect it to work. ☹️
You can contact the creator and ask them to update the cc if you really want it.
Just to be sure, try to remove all of them and see if the game works better.
For example, move the mods folder from Documents > Electronic Arts > The Sims 4 to your Desktop and start the game.
If that works but you want to keep your mods, you can try some different things to sort out the ones not working:
- If your problem occurred after a certain mod haul, remove all these new mods (see if the game works), and then add back a few at a time, restarting the game in between until you see the problem occurring again. Remember that you can possible have several broken mods.
- If the problem started after the latest patch/update, always make sure to update your mods when you update your game. Check this list out for some mods that were broken in the C&D-patch! A few others have been broken after but not so many that there is a list.

- Like the first "solution", but for all your mods. Remove all and put back some at a time to find broken ones (last resort if you have like 1000 mods).
Good Luck!
