@MojoJojoTMMMove the game folder to the desktop, fix the game in Origin
Origin/Library -right-click on TS4 - option "Repair game"
You have to wait until Origin will fix all packs, not only the base game.
Launch the game and a new game folder will be created.
Start a new game with random sims and check if you still have this error in this new folder.
Is so, you need to reinstall the game.
If the game is working properly delete in the new game folder following folders: "saves" and Tray.
Then go to "The Sims 4 old" folder and copy - your "saves " folder, and paste this folder in a newly created game folder.
Do the same with Tray folder and TrayDeleteItems file
Check if there are newly updated version mods you are using.
Then copy and paste your mods and CC from the old mods folder to the new one. First copy the scripts mods every time checking if the game is working properly. If you have a lot of CC try 50/50 method ( divide your CC into smaller batches for example 50 pieces in one subfolder and check these subfolders one by one
Launch the game and check if this problem disappeared in the old save
