Manage World Loop

Hi

I play on a Macbook, M1 2020.

Last night I was travelling from a bar back to my home and it put me into the manage worlds and asked me to create a new Sim. Anytime I tried to enter someone else's home, or my own, it was just stuck in an endless loop.

I left the game without saving but when I tried playing again today I am once again stuck in the loop. (To note here on my old MOD's, they have been working perfectly since the recent update and I've had zero issues - I also only play with like 4/5 of them)

I have done the initial troubleshooting where I did a 'factory reset' and then re-added my save. I also made sure to completely clear all my mod's to see if it'll work without any of them but nothing is working.

I, pretty stupidly, only play a single save and I have nearly 450 hours on this single save so to find it unplayable is pretty devastating. Can anyone advise?
