@Lbaekr2435 Since the game loads without mods, I'm thinking you may have one or some that are broken. First make sure you have the most recent versions. Check with the mod creators to see if they've updated them recently. Once you're sure you have the most updated versions, I suggest testing your mods/CC a little bit at a time. If you 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. Before opening the game with the half you're testing, delete the localthumbcache.package file located in the Documents / Electronic Arts / The Sims 4 folder
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.
