You haven't mentioned if you use mods or not, or if you've tried resetting the Sims 4 folder.
Here are some troubleshooting steps to try.
1. Move your mods folder to the desktop, delete the game cache as well as the localthumbcache.package from your Sims 4 folder. [C:\Users\Username\Documents\Electronic Arts\The Sims 4]
Try a new save to test to see if your issue goes away. If so, you will need to go through your mods folder to see what need to be replaced.
Game updates can cause issues with mods and custom content. These may become outdated with each new game update.
Please check with the creators to see if there are updates to the mods and cc you use.
