Sims 4 Gallery Problem

I had this problem with everything in the gallery. I even tried to delete one of my families from my library, but it just froze and I had to go to my task manager to force close the game. Nothing on my gallery is working. I've tried for days now to place a lot into my game with no success. I've gotten as far as having it load into the lot, but the game gets stuck on the preview before you can move around in build mode. I even deleted some mods from my game, thinking that they were the issue. Nothing. Nada. Zip. Zilch. Zero. Every single time I try to load/place/save ANYTHING from the gallery, I have to force close the game.
