sims 4 won't start

I just got a new laptop since I needed more SSD room for everything. I installed the ea app and all of my sims 4 expansions and base game and kits, all of that stuff. Now it is saying that it is damaged and I need to repair it because it won't start. I have repaired it 3 times and reinstalled it twice. It still will not work. Any idea on what I can do?
