Endless loading when trying to load any household (specific save)

I opened the game after playing the last time in January, and I am getting an endless loading screen when trying to enter any lots in live mode for my game. I usually play with CC and mods, but I removed my mods folder, recovered to the oldest save possible, and am still getting the same error. At least by recovering to an older version, I can open that save and load in the lot itself, but not in live mode. I had no issues before this. A couple of things that might be relevant are that I have some graves and ghosts in my lot, lots of plants for gardening, and last time I played, a stayover event was running. But I believe that in the older version I recovered, the event wasn't happening yet, so it might not be related to the issue. Is there any way to save this legacy save file? I am able to go into live mode in other saves.
