Infinite loading after December 2023 update

Help pls! I've encountered an issue with the game since the December update 2023 with all mods deleted. 

Issue: After I updated my game, purchased the For Rent pack, and updated my mods, I couldn't load a particular household(the problem household). At first, I clicked resumed from the main menu then it was loading for 30min till i had to force quit the game. Loading usually takes very little time for my Mac and I've never encountered this issue.

I reopened the game and instead of resuming I loaded my last save, played a different household and invited the sim from the problem household--all worked great. I switched control to the problem household sim while she was Not at home lot--all seemed fine until I sent her home back to the problem lot and the game was stuck loading infinitely. Had to force quit again.

I deleted the lastexception file, localthumbcache file, the mod folder, disabled mods in game setting and repaired my game from Origin.

Went back to the game-->build mode from world map-->bulldozed lot-->evicted household-->quit game-->reloaded the problem household it seemed the issue was gone so I downloaded the same house (no CC house) back to the lot-->couldnt load all the furniture, couldn't delete or add anything build mode-->force quit-->reloaded problem household but downloaded a DIFFERENT house and it seemed the issue is gone. As soon as I re-downloaded that old house from the gallery--> go back to world map, I'm having infinite loading screen again.

*I doubt the issue is from the actual house itself (not the lot but that particular house) as i've been using it for so long and suddenly after an update there's an issue.

Any help is greatly appreciated! Thanks <3
