Sims 4 Won't Load

Since I updated my game, it won’t load past the screen that says "The Sims 4," and I keep getting an "Application not responding" message. I’ve tried everything: I removed my mods and custom content, but that didn’t work. I also attempted to repair the game, but that didn’t help either. Finally, I even uninstalled and reinstalled the game, yet I’m still experiencing the same issue. Is anyone else having this problem? What else can I try to fix it?
