Sims 4 Keeps Closing Unexpectedly

Hi!

I've been playing sims for a couple of weeks after updating and deleting all broken mods/cc and it was working absolutely fine. But the last couple of days I've been playing, it'll close randomly without warning and then I aren't able to save my game. It has done it  mid-play, mid CAS and mid build mode. I've done all the necessary things required in order to get it to work but it's not doing anything and seems to be doing it more frequently. 

I play on my MacBook Air, all up to date.
