@oreosimmer01 Hello! I'm no expert at reading the exceptions but in the last LCE you posted, it looks like most if not all the errors are coming from the basemental mod. Try taking that one out and testing the game. You might need to check for an updated version. There may be other mods or CC causing issues though. It looks like you have quite a bit so I suggest testing your mods/CC a little bit at a time and delete the localthumbcache.package file located in the Documents / Electronic Arts / The Sims 4 folder before opening the game for testing. You probably want to create a new game for testing so you don't make any changes in your current save until you find the one(s) causing the problem. If you do have a lot of mods/CC, the 50/50 method works best.
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.
