@Sofifa57Before you start reinstalling, try to fix it differently.
Go to Documents/ElectronicArts - inside will be The Sims4 folder
Step 1. Rename The Sims4 folder to "The Sims4 old"
Step 2. 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.
Step 3. Turn on the game - a new game folder will be created and you will have two - one old, one new
Step 4. Check if you still have this problem in the newly created game folder. Start a new game with the random sim and check if your game is working now properly.
If everything will be OK let me know and I will describe to you how to recover your all saves and library.
I don't work for EA
