Cannot get game to load

I am also having a crashing issue that popped up today--it was fine yesterday. I can get into my save file but then when I try to either build or play as any family (mine or randoms in the world), the game crashes on the loading screen. I've cleared cache/repaired game/restarted/messed with visual settings/done all the things I'm supposed to do (and I don't even use mods) and nothing is working. The game is effectively unplayable for me right now.
