Infinite loading screen after main menu, unable to load save.

Hi! A few days ago, I started getting an infinite loading screen when trying to load my family's latest save.
I tried the 50/50 method several times. I discovered that my family would only load after deleting the custom furniture content folder from the "mods" folder. I was sure the problem was a corrupted furniture set, but it turned out that wasn't the case: I moved all the mods from that folder to the desktop in small groups, and when I opened the game and clicked "Load Save," it loaded without a problem, and I was able to play as that family. This works for each furniture mod group SEPARATELY. But when I moved all the furniture-related custom content back to the Mods folder, the save froze again, and the loading process continued endlessly. Besides the 50/50 method, I've already tried updating all furniture to DirectX 1 in Sims 4 Studio, clearing the cache and replacing the resource.cfg file, and resetting the game to factory settings (then replacing the new "mods," "saves," and "tray" folders with the old ones), but this ultimately didn't help. I'm not sure the problem is with the mods, because if I create a new save with a new family, it loads without a problem. If the problem is with the corrupted save (the one with my main family), then why does it load without a problem when I delete the "furniture" folder from the "mods" folder? I don't understand anything((. I would be grateful for any other solutions to this problem, as none of the above methods helped me.
