Sims 4 keeps freezing in CAS

Sorry for the late reply, I've been pretty busy getting ready for my upcoming holiday, but thank you so much for the reply!

At the moment, I only have the sims 4 base game, so no vampire toddlers, however, it does only seem to be a specific household which causes the game to freeze. I removed all my cc from my mods folder, added 2 random sims from the gallery, and was able to change the outfit category just fine. I re-added the household I am currently using in game, (one female sim & a toddler), went to change the females outfit category (to formal), and the game crashed, as usual - the sims music stops, the game freezes, as does my PC. I am unable to do anything, I can't move the mouse, exit the sims via the F1 button or windows button, etc - I have to turn the laptop off via the power button. It seems that the specific household is the problem, even without cc, which makes no sense to me, I've never had any problems like this before!

Thanks,    amelia.
