Hello,
I assembled the Picar-X exactly according to instructions with Raspberrypi 4. All of the examples work fine except the camera.
I checked the FCC cable on both ends and they are perfectly in place.
Console logs:
$ libcamera-hello --list-cameras
No cameras available!
$ libcamera-hello

It looks that the camera is not being detected at all.
UPDATE:
I am able to take a picture using this command:
sudo raspistill -o test.png
