The Sims 4 game won't start

I'm back and my game still won't launch. I have tried just about every suggestion I can find on these forums. My issue started about a year ago. Since then, I have spent hours chatting with EA Support, they weren't helpful. I have deleted everything EA and The Sims and reinstalled it all from scratch using the EA app. I purchased expansion and game packs which seem to launch the game on the initial try, but then it freezes on the loading screen. I have to use Task Manager to close the game. After that, it will not load again. I have updated any and all drivers that can be updated on my machine. I have purchased The Sims 3 and that loads and plays fine on the same computer, but the Sims 4 refuses to. I am at my limit and could really use some help...
