Assembled the PiDog and everything works except the camera.
I checked the connections based on the diagrams and photos in the forums. They look same except instead of blue color on one side, the cable connector is black on one side.
Here are the outputs from the Pi 4 B.

@SunFounder_Moderator I have posted images of the camera wiring earlier in this thread.
libcamera-hello output is also in thread.

Unfortunately, I don’t have another FFC cable. I did take it out and tried to connect it couple of times but the camera is not detected by the Pi in libcamera-hello
I had a similar problem. Directly above the camera lens there is a tiny flat cable with a rectangular tan coloured tab on the top end. The back of the tab is a connector that plugs into a tiny connector behind it. Press on the front of the tab and it may snap into the connector,
That worked in my case.
