Re: Sims 3 won't open: Alder Lake (Intel 12th-gen) CPU
@wiry961 The issue here is your processor: Sims 3 doesn't load properly on 12th-gen Alder Lake CPUs. You have a couple options here. You can try using this PowerShell script another user posted:
Or you can use Process Lasso to limit the game to one CPU core while it's loading. You'll want to close Process Lasso once you have a save loaded for better performance.
I also want to point out that your dxdiag lists a few Windows update failures and a number of crashes of the Dell Alienware Command Center. For the latter, Dell released a new version a couple of days ago, and you can get it here, along with any other updates for your system:

For the Windows update issues, try manually running updates through Settings > Update & Security. Let me know if you get an error; otherwise, just let the updates install and then restart your computer.
