Sims 4 Won’t Load With Mods

@DaGamerPerson Hello!  I agree with @Coley666 that you should test the game with a only a few mods and CC at a time.  Every time there is an update, there is a potential for mods and CC to become incompatible with the game.  You could start by organizing them all into categories.  Perhaps you could everything to separate folders on your desktop or to a thumbdrive.  For CC, create individual folders for CAS and BuildBuy items.  Then create subfolders for CAS items (tops, bottoms, makeup, hair, etc.) and BB items (living room, bedroom, bathroom, etc.).  For the Mods, you could try to separate them into function like UI, BuildBuy, Game play, etc.  Another option might be to group items by creator.  Then, when you're adding things back to your game, try to make sure they're no more than one folder deep; ie. Documents>Electronic Arts>Mods>*furnitureCC   I also suggest deleting the localthumbcache.package file located in the Documents / Electronic Arts / The Sims 4 folder before opening the game for testing.  That cache file can carry over effects from mods.  Once you've identified any problems, check to see if there are updated versions.  It may take a while to get through them all but it will be worth it to get your game back and, having your mods / CC organized should help you identify problems later.
