Error code after new patch and new DLC when i try to play my household

I had this error code and did a 50 50. My KiaraSims4Mods, specifically the gigs, were the problem. Just went over to her site and it looks like they were updated a little bit ago. Not sure if you have any of those mods, but that could be your problem or any mod that uses the freelance system maybe. I haven't found any specifics as to why that error code was thrown yet.
