I had similar issues with the original camera.
But after days of testing even with the official radxa image I think I found the possible problem.
There is a batch of boards with a wrong csi connector, the pins are not correct.
I found it here: https://github.com/radxa-build/radxa-zero3/issues/15
I send a mail to my supplier and they will send me a fixed cable, I can give an update if it's fixed.
