Stuck on Loading Screen after downloading DLC

I installed 4 new DLC into my game and opened the game to create a new sim. Everything was fine up until I tried “Starting New Game” or entering Create a Sim. I could go to the worlds and choose a home for my sim but once I clicked play, it stays on the plumbob loading screen. I can see it spinning at the tips still, it’s been loading for almost an hour now. I don't know what to do. I don’t think it’s my CC or my mods because they worked before I bought some expansion packs. Pls help
