Sims 4 keeps crashing

Hi, 

I have installed the Sims 4 + get to work and it has been running great for awhile, but since a couple of days, it just keeps crashing. This is what mostly happens: 

My sims are just doing their things and all of a sudden they keep doing that same thing. Everything kind of freezes, but they still move on the spot (such as one kid was doing her homework, and she just kept on writing and writing and writing). Sometimes it stops when I adjust the time speed or when I switch to build mode (then they mostly debug and stand up right beside the object they were on or working with), but it has crashed completely two times now .

What is wrong? Also, I didn't really understand if I had to apply the fix, since I already have the latest version with get to work?

Hope someone can help.

well i have the same problem and it seems to be in the update,there is a new patch out that should fix it,it is only not cracked yet so we have to wait
