Unfortunately, that's another one of my problems. If I could, I would do it now, but I can't log into Discord. I've never been able to, I don't know why. Unfortunately, mod authors and all support are only available through Discord or Patreon, which I also don't have, so I'm out of luck. But thanks anyway for the advice and trying to help.
@SweetySimon Please test with no mods at all: Exit Sims 4 then drag your Mods folder to your desktop. Then delete the file called localthumbcache from Documents > Electronic Arts > The Sims 4. If you think you might accidentally forget to exit without saving after testing, copy your Saves folder to your desktop too, to back it up. Now open Sims 4 and see if you still have the problem. If you don't, you can start the process of figuring out what from your Mods folder was causing it.
