[CL] [LS] White Screen/Endless Loading when loading world with penthouses

Hi, I'm having the same issue. This problem occurs on my year-old save, I've never used any mods or CC. Whenever I try to load my save it gets stuck on infinite loading screen. I managed to get back to my save once through "resume game" a couple days ago, but when I tried to travel with my sim it got stuck on infinite loading again. The last time I managed to successfully play and save the game was on 12th of September so I wonder if this has to do with the new update.

I've tried restarting my computer, the EA app and the game. I've tried repairing the game two times now, no success. I followed the steps on the previous comment about the LastException files just a moment ago and this is what the current one says:

I appreciate any advice on what might be wrong here. I've never had this issue this bad before.
