This is known to be caused by broken Mods particularly an old version of MCCC so remove all Mods/CC and look for updates.where you got it.
Hello, i got same error and that error still there. Did you fix? Can you help me?
@Senasenaa Please test in a clean user data folder. Move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content. Don't add anything to it yet; just start a new save and make sure it works properly.
If it does, you can copy one of your saves from the old Sims 4 folder to the new one, and see whether it works. (Saves are located in the saves folder.) If the save loads normally, you can start adding your mods and cc back in batches, testing each time to make sure the save still works. Any batch that causes another error needs to be split and tested until you find the problem file(s).
If your save still throws an error in the clean folder, try a backup save instead. Use the manual method in the link below, and transfer one backup at a time to the new Sims 4 folder.
