Endless loading screen when attempting to travel to a Custom lot

I been having an issue where lately, whenever i try to load into a lot (whether its through live mode or build mode) i get stuck at an infinite loading screen. What's especially frustrating about this is the fact that i USED TO be able to load into and play on these a few days ago, then suddenly, As i progress through my save, they no longer want to load. I thought it was due to some broken cc, but when i tried the 50/50 method with the cc, and deleted some of the items that may have been causing problems, at first I was able to finally enter the builds through build mode, but as soon as I attempt to travel to the lot with a sim, I got stuck at the loading screen again. Like I said, I was able to enter these custom lots with no problem for a few days, so i know my pc is able to handle the amount of cc, i just want to know why they suddenly don't work anymore. I haven't downloaded anything new either. I even tried to create an entirely new save with a new household, just to test if that old save may have been corrupted or something, yet still no luck, and getting stuck at indefinite loading screens. I even checked with the creators of the lots to see if the cc they used was still compatible with the latest version of ts4 and they said they should be, so i am just at a complete loss as to why I am no longer able to access these lots. I have a mod that would allow me to find an exception within build buy mods, but I can't even utilize it if i am not even able to load into the lots. My main concern is just to figure out how these lots were perfectly functional before and now suddenly aren't. Would really appreciate some guidance 🙂)
