Hi, I have been using the Camarray HAT with the cameras integrated with the kit, Arducam -16MP-IMX519.
I put some cable extension for all 4 cameras like shown in photo:
setup:
Raspberry Pi 4B
64bit

I got this error when I use libcamera-hello:

I cannot see the cameras.
I checked several times the connections and changed the cables and there are good.

I installed the kernel IMX519 driver slow speed.
Let me know if you need more info
I would really appreciate your help
Do you know I can I fix it?
