Don't know what happened to my first posting of this.

I can successfully get a jpg image from my IMX219 on my raspberry pi, and MotionEye knows the camera exists, but when set up only displays a solid grey image.

I've tried sudo modprobe v4l2_async and sudo modprobe bcm2835-v412 and sudo modprobe v412_common to no effect.

The folders dev/video0/ exists, though MotionEye says it's using dev/media2 for the camera that isn't working.

I have an external USB camera working in MotionEye without problems. I've stopped and started MotionEye multiple times, and rebooted the Pi Zero 2.
