Brand new PC: Game keeps randomly crashing

linalush​  Your newer dxdiags have more crashes of one of the graphics drivers, and the one BlueScreen is also related to video driver.  It's concerning that reinstalling the drivers didn't fix the issue.  So I would suggest testing Sims 4 on the integrated graphics chip, to see whether the problem is the Nvidia chip or something else.

Open Windows Settings > System > Display > Graphics settings, find TS4_x64 on the list, and set it to the power-saving option.  For the Nvidia App, I don't have it installed and don't know what options it offers, but you'd be looking for something that allows you to choose integrated graphics for TS4_x64.  The Windows setting is usually sufficient, but I'd check here too just in case the Nvidia App tries to override it.

To be clear, this is not a fix, just a test.  If the game works normally, then we've narrowed down the problem to the Nvidia graphics pipeline and can go from there.

Dustlex​  It shouldn't be necessary to specify the Nvidia GPU in Windows settings, in fact I haven't seen a case where the system chose the iGPU in years.  And you can clearly see from the image in the OP that the GPU was active up until just before the image was captured.
