This issue now seems to be fixed in the 1.68.154.1220 November 2020 patch.
Thanks all for confirming it now seems to be fixed. If you start experiencing issues again please post 🙂
I have a 2019 Retina 4K display iMac with Catalina (Version 10.15.6). 32GB memory, 3.2 GHz 6-Core Intel Core i7 processor and Radeon Pro Vega 20 4 GB graphics. Experiencing similar issues. Game loads up perfectly fine as it did before but as soon as the game lags slightly, the whole game freezes, gets the rainbow wheel and often requires me to force quit or even restart the entire computer. When it freezes the world and the house seem to black out and sometimes the whole screen goes red.
Have tried every fix I can think of, all mods were updated before updating the game, removed mods after this started occurring, tried repairing game twice and removing cache file. Game is practically unplayable after this and does not appear in the "My Home" menu in Origin. Did not happen before patch.
