Screen Tearing!

@SamH1982  I'm glad to hear the game is working again.  Just to follow up on a few things, a clean uninstall and reinstall of the drivers would reset all the Intel and Nvidia graphics options to defaults.  The Nvidia Control Panel also has a reset to defaults option, which works fine on its face, but your dxdiag showed a couple of Nvidia errors, so reinstalling was the right move.

Hopefully you used the drivers Acer provides for your laptop:

On a machine this new, it's best to use the drivers provided by the manufacturer rather than the more generic ones from Intel and Nvidia.  I'm not saying you need to uninstall the generic ones if that's what you used, only that it's something to keep in mind if you run into more issues in the future.

The unrecognized graphics card is due to your GPU's device ID not being in the game's database.  It's not a problem, as you can probably tell: the graphics options are set to Ultra anyway, and that's all the device ID helps with.

Finally, it's worth making sure that Sims 4 is still using your Nvidia graphics card and not the Intel chip.  Go into Documents > Electronic Arts > The Sims 4, open config.log, and you'll see the GPU the game is using listed about 30 lines down.  Let me know if it's the Intel chip; if you see the 3070 ti, you're fine.
