Try this:

  3. Disconnect your computer from the internet by removing the network cable or turning off your Wi-Fi and/or modem. Leave disconnected throughout this process.
  4. Run DDU, this will remove all display drivers from your computer, with the exception of the default Windows driver, and remove all settings of those drivers.
  5. Reboot the computer once DDU has finished it's work.
  6. Once rebooted and at the windows desktop, run the installer for the nVidia drivers.
  7. Reboot the computer again once the nVidia installer is finished.
  8. Once rebooted, reconnect you computer to the internet/network.
  9. Run the game and see if the issue has been corrected.

nvmgf2umx.dll crashes are commonly caused by glitched, mixed, or conflicting driver files and settings.
DDU will completely remove all files and setting, thus removing any of the above issues. Even when you use the nVidia "Fresh Install" option in the Custom Settings of the driver installer, it doesn't actually clean "all" of the above issues, so by using DDU to can actually perform a "clean install".
Disconnecting the computer from the internet/network during the DDU cleaning and fresh driver install prevents Windows Update from taking over and trying to install drivers from the Windows Store, which in doing so can re-introduce the above issues.
