You are a genius!!! After patrolling this page for days on end, your solution for me worked! I had tried everything everyone suggested 30+ plus times. You get a BIG thank you from me!! I also never post anywhere either but this is necessary as I have spent countless hours trying to fix my game.
What I did and I HOPE this works for other people- I went to system preferences/battery/battery and power adapter and unchecked the automatic graphics switching box. Mine does work for some reason and doesn't revert back. But if your does revert, I would download the program they are talking about. I loaded up the game and switched all my settings for the highest and best possible graphics capable to test it, because this brand new laptop ~should~ be able to handle it!! I went into a household and spun the camera around for 5 minutes straight in all different directions. It did NOT produce the spinning wheel, glitch, freeze, crash, or anything. Which it would have before in the first 10 seconds of loading in. It's running as smooth as ever now. I will continue to play, and if something goes wrong again I will report back. But, no news is good news. I really do hope this works for everyone else because I just about pulled my hair out.
Thank you again @joho1144
FWIW I am still running Catalina and used the gfxCardStatus app to manually override the graphics card settings, and the game appears to be fixed for me in my very limited testing. Personally, I did not and will not install Big Sur as a beta just to “fix” The Sims.
