@mw1525 Sims 3 requires .NET Framework 3.5, which includes 2.0 and 3.0, but if the runtime were missing or corrupted, the game wouldn't open at all. And this is a Windows feature, not dependent on your hardware.
Still, if you want, you can try uninstalling and reinstalling it: click Windows key-R, enter "appwiz.cpl" without quotes, click "Turn Windows features on or off," and click the box next to .NET 3.5 to uninstall it. Restart your computer and repeat, clicking the box again to install, then restart again.
Sims 3 also uses DirectX 9 and VC++ 2005 x86, and here again, the game wouldn't open if the runtimes were missing or corrupt. But if you'd like, you can reinstall both. You don't need to uninstall DX9; just run the installer over the top.

VC++ 2005 does need to be manually uninstalled before reinstalling it.

If reinstalling these runtimes doesn't help, or you don't want to go through the process yet, please post a dxdiag.
As for what else might cause this issue, I'm really not sure and would rather have at least a little more info before I start throwing out wild guesses. By the way, did you try the GPU Add-on tool from NexusMods? I understand why you might be reluctant to try it, but it's easy to reverse its effects: just save a copy of your current .sgr files and restore them if necessary.

@mw1525 My computer doesn't list any .NET frameworks in the Control Panel list either, but if I click "Turn Windows features on or off" (it's available on that screen too), I can see that both 3.5 and 4.8 are present. I would guess the differences are that your Iris Xe laptop has .NET 5.0, which apparently has the privilege of being listed; and that Windows 7 lists .NET by default, or at least 4.5.
The only other difference I see between the two Windows 10 lists in your screenshots if that the AMD PC has two extra 2005 VC++ runtimes. That's not a problem, and maybe some other programs are missing further up or down the list, but otherwise the entries are identical. The Windows 7 PC has a whole pile of 2005 and 2008 VC++ runtimes, probably a result of Windows just installing the new versions at every major release rather than simply replacing them.

@mw1525 Whenever you do get back to this, if you want to try something random, install Seasons and see what happens. Another player in a different thread said they had weirdly low-quality graphics in Map View until they installed Seasons. I don't know why this would be, and they had both a different issue than you and a different GPU, but it would be easy enough to try, especially if the next step is uninstalling the game.
I'll PM you the link to the GPU Add-on tool in case you change your mind about using it or at least want to see what it is.
