Save not loading/Infinite loading screen

I’ve been playing this same save for months, and I’ve been recently playing it every day for weeks. As recent as yesterday evening, there were absolutely no issues. This afternoon, I tried to boot up my save, and it wouldn’t load. The game itself opens just fine, but when I press the resume button, it gets stuck on an infinite loading screen. It doesn’t crash, it just keeps loading. I don’t know if it would eventually load if I let it sit for hours. I’ve tried everything I could think of. I tried 50/50 with my mods and cc, didn’t help. I repaired the game, didn’t help. I took out all of my mods and cc, didn’t help. I let the game generate an entirely clean Sims 4 folder and then only added back my save, didn’t work. When I click the new game button, it takes me to CAS and that works fine, but it won’t let me actually play the game past that. I really have no idea what to do. This save is on gen 4 and I really love it so I really want to get it working :[

UPDATE: Got the new game to work fine, the game functions in a new save with all of my mods like usual. I have genuinely no idea what could be wrong with my regular save since it was working just yesterday :/

UPDATE 2: Oh my God it was their house. It was their house the entire time. 6 hours of troubleshooting and it was the house. I tried building on their lot without actually loading the family and my game crashed, so I moved them to a different lot and it worked. I have no idea what was possibly wrong with the house but there you go. Good lord. I’m gonna go build them a new house.

UPDATE 3: Okay, well now we have a new problem. What in the hell is wrong with this lot? I placed a new house there and it didn’t crash, but I decided to check it out in build mode before moving anybody in to see if there was issues. I think I found the problem, and I have…no idea what’s causing it. I attached a video to show the problem. What in the world is this…fog??? If anyone has any idea, let me know, because I sure don’t lol

UPDATE 4: Turns out it was just the view distance, the game reset all my graphics settings when I started on a clean file. No weird bug this time. Hallelujah. Hopefully there won’t be anymore updates to this post lol
