Hi,
I have an RPI Bullseye with a Camarray Hat module to sync 4 HQ cameras together. This is the camera that I have: Raspberry Pi High Quality HQ Camera [12MP] : ID 4561 : $50.00 : Adafruit Industries, Unique & fun DIY electronics and kits.
Unfortunately, libcamera does not preview the cameras and I am not sure what is wrong with it. This is the error that I get when I run the preview command:
libcamera-hello
Preview window unavailable

Would appreciate it if anyone knows how to fix this issue. Please let me know if you need more info.
Thanks
