Sims won't interact with object

hi,

I seem to have an error every time I play the game. I looked in Last Exception and it said something like (AttributeError: 'Somewhere' object has no attribute '_require_carried' and the error module is constraints.py . Whenever I play my game my sims can't interact with objects. For example picking up babies or sit down on the couch, the sim doesn't move. It's not completely frozen because the sim can still walk somewhere, just not interact with objects. I've tried everything to fix it, update the game, delete all mods, uninstall the game but nothing works. I'm basically unable to play now so I really hope someone has a solution.
