Can't play new saves

After the last big update with all the new stairs stuff, I've been unable to play new saves. I click new game and start the save, then I pick a lot to move the household into. When I get to the moving screen where you choose furnished or unfurnished, I click the confirm button and my game freezes. Then I have to alt+f4 to close the game, but it never closes, so I have to shut down my whole computer just to close the game. However, I was able to go into an old save and move to different lots. I've tried to run the game with no mods or cc, and I repaired my game, but it still didn't work. I also made sure my computer is updated. I don't really know what else to do lol
