@BrittanyAkina Are you really saying Sims 3 has launched on this computer at some point? I ask for two reasons. One is that your dxdiag is full of DirectX 9 errors, and the game won't open at all until this is addressed. Maybe you've done so already, and the errors are from before, but if not, please manually install DX9 now, as described here:

The other reason is that the deviceconfig.log is from an entirely different computer, perhaps your old one if you moved over some files. The log should update every time the game actually loads, so either it's never loaded or the file is being synced from somewhere else, or you're looking for the file in the wrong location. To make sure it's the correct file, right-click on it and select Properties, then General, and look for the file path in Location. It should be exactly this:
C:\Users\[your username]\Documents\Electronic Arts\The Sims 3
If the file path is different, please look in the above location. If the file path is the same, do you use OneDrive, and is it set to automatically sync the contents of Documents? That could be the cause—OneDrive is downloading an old version of deviceconfig—and the underlying problem—OneDrive is also downloading other files that are getting in the way.
If you're not sure whether OneDrive is set to automatically sync Documents, here's how to check:
