Hey there, thanks for including your DxDiag as well.
Since the game is getting through the anticheat and only locks up once it switches to fullscreen, this sounds more like the graphics/display side of the launch process hanging than a problem with the installation itself.
Based on what's showing up in the DxDiag here, I'd try disconnecting your second display (or switch Windows from Duplicate to PC screen only) and see if the game launches normally.
From there I'd also try closing any applications that hook into games or the GPU (MSI Afterburner, RivaTuner Statistics Server, Discord overlay, GeForce overlay, Game Bar, RGB software, etc.). If that doesn't help, try a clean boot and test again to help narrow down what could be conflicting with the launch in this case.
