Sims 4- Single Lot keeps crashing

I am really at a loss here on how to fix this problem, so hopefully someone can help me. There was a lot I was building on last week that crashed while I tried to save it to the gallery. Since then this single build on this lot does not work. The whole save works perfectly, but as soon as I try to replace it, go in to build mode, or even try to visit it in live mode with a sim, my game always crashes. I cannot get back onto the lot no matter how hard I try. I have removed all my mods and cleaned up my folders, but nothing has seemed to work. I have the last crash exception file, but since it was from last week, I can't use The Sims 4 Last Exception Assistant to translate it. I really don't want to have to delete the save, but I'm not sure how to get rid of this.
