@josebionictiger Hi! This looks like a mod conflict. Try moving your mods, maybe to a new folder on your desktop. If you move the whole mods folder out, a new one will be created when you open the game. Once the mods are out, delete the localthumbcache.package file located in the Documents / Electronic Arts / The Sims 4 folder before opening the game for testing. If everything is working without mods, then you might first check for updates. You could also test them one by one, to see which one is causing the problem. If you have a lot of mods, try testing half at a time. NOTE: You might want to make a new save for testing so you don't inadvertently change your current / favorite save. If you do use a current save for testing, do not save when exiting the game. This is the process I use for testing mods.
1. Divide your mods/CC in half (maybe make a folder on your desktop to hold the half you're taking out).
2. Delete the localthumbcache.package file again, before opening the game with the half you're testing,
3. If the game works with that half, test with the other half. (Again, delete that cache file before opening)
4. Once you know which half is causing the issue, divide those in half and test again (delete the cache file again).
5. Repeat the process until you find the culprit.
