My Sims 4 Game is not working.

I don't know what has been going on, but ever since I bought Seasons, my game hasn't been working right. Whenever I try to load a family, there is a loading error (forgot the number) that tells me I should relaunch the game. When I do relaunch the game and try again, sometimes the error pops up again, but when it doesn't the game just loads and loads forever. I can never play a family. Yes, I've tried playing different families, yes, I've moved houses with my current family. Yes, I've checked my mods, yes, I've reinstalled without uninstalling, and yes, I've uninstalled the entire game. It could be wicked whims or the mc command center, but I've updated both of those, put them in, and the game just kept loading forever so I couldn't tell if they didn't work or not. The other day I had put in certain mods to try and see if that would work. The game loaded and I got to play for a good two days (actual), but then I tried to put in more mods to see which ones would work, and which ones wouldn't, but the game just broke again. I don't know what else I can try. I just really miss playing the Sims. Any help?
