Can't play game

I bought and downloaded the new sims 4 life and death expansion pack and now I can't open my sims 4 game and play. As soon as I click to load the sims 4 it freezes on the green icon before it can pop up and then the whole window closes and I get a pop up on my computer that says "unable to start: initialization error at start up." My game worked just fine until I downloaded the new expansion pack. I tried removing all of my mods and cc, it still didn't work. I then tried moving my whole sims 4 folder out of the EA folder and I put it on my desktop and tried to open the game again, after that, the opening screen gets a little farther before it freezes and again closes out with the same pop up error message. Any ideas on what I did or how to fix it? Also would love to not loose my current saves and progress....
