Last UI exception files aren't readable for support. Please try this exact sequence of test steps:
- Drag your whole Sims 4 folder from Document > Electronic Arts to your desktop.
- Run a Game Repair in the EA App. (If you use Steam, the equivalent is Verify Integrity.)
- Launch Sims 4. You should get no list of mods on launch, and you should have no option to load a previous save. Reset your Options.
- Start with New to test if your issue recurs in a new game.
If that works, you can try adding mods back if they are updated or confirmed compatible with this patch. See the current Broken & Updated Mods & CC lists and Previously Broken mods and CC
