Hi AgallenSMX,
Below command can get video preview and can be closed properly with Ctr + C. The same as the command in your comment#6.
gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! 'video/x-raw(memory:NVMM), width=(int)3280, height=(int)2464' ! nvvidconv flip-method=0 ! 'video/x-raw, format=(string)I420' ! xvimagesink -e
Can this fix the “pipeline-close” issue?
BTW, we have an ISP file for our IMX219 module in case you need it. You should be able to get better image quality with this file.

Please copy camera_overrides.isp to /var/nvidia/nvcam/settings and do below commands to install the ISP file.
sudo chmod 664 /var/nvidia/nvcam/settings/camera_overrides.isp
sudo chown root:root /var/nvidia/nvcam/settings/camera_overrides.isp
