Unable To Load Other Lots / Households

I have removed my mods but even then, I'll go to manage worlds and click on a household that isn't my last played household to play in. An error message will show up and tell me to reload the game. I do it 20 odd times and nothing happens. I waited for the new update, thinking it would fix the bug. It did not. I tried to access the household by switching in live mode but an error came up again, so my sim couldn't even visit that household's home lot and then suddenly, I was not playing in my last played household anymore. Whenever I tried to build, nothing would load, so I was stuck on the loading screen for an hour once. Only Create-A-Sim is working correctly. Otherwise, the game is pretty much unplayable. To make matters worse, every time I try to close the game, Steam says "stopping" but the game never actually closes. I have to turn off my laptop completely to force the game to close.
