Hi @Hayleigh501 There are a few possible things going on. One, make sure that you don't have OneDrive synced with your Sims folders.
Two, if you've been playing with any cookbook/recipe mods, update those and put them back in then try again. One possible cause of this issue is having removed a cookbook mod without first removing plates and food associated with it. Also, delete the file called localthumbcache. If the food mod update lets you back in, you can delete associated recipes etc.
If you still can't get into that household, try loading an earlier version of the save.
