Specific Corupted household

helena_21_fs​  Please open Documents > Electronic Arts > The Sims 4 and delete any lastexception files you see.  Try again to load the original household, in the original save if you'd like, and look for a new lastexception.  If you find one, open it and delete its first line of text, then attach it to a reply here.  Alternately, you can copy the text and paste it into your reply.

Please test with your Mods folder removed if you've added anything back to it, at least for now.
