I restarted with nvidia and the card is back but the drivers do not
work. Currently driver 455 is selected to be used but the primary
selection is intel (see below)

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. 
Make sure that the latest NVIDIA driver is installed and running.
