Unable to get a pi camera to work. Is this the only OS that'll work on this board?

Been having issues getting the CB1 to work with the Bigtreetech Pi4B adapter and I cant get the camera to work. I get nothing out of the HDMI port.
I've tried to run other versions of Pi and nothing happens. The Pi4B adapter shows no LED's for power or activity and had no indication it was working other than once I tried this OS I was able to see the Ethernet port lights light up. but I get absolutely nothing when trying other versions of Klipper or even octopi.
I've tried contacting BTT support but that's a joke. I dont think even though they sell a lot in the states that they have anyone that comprehends English in their support department as it's like speaking with a bot when emailing their support as their responses are oblivious to the issues I requested help with so I figured I'd try through here.

Start by reproducing the CB1 setup with the Bigtreetech Pi4B adapter, camera, and the OS images mentioned in the report. Check the HDMI output, adapter power/activity LEDs, Ethernet link lights, and camera behavior; done requires identifying whether the board and adapter work together and documenting which OS versions and peripherals are supported.
