I have gone through multiple posts but failed to find a fix for this issue.
When OAK FFC 4P module is connected to cameras on A and D port it failes with an error as attached in the terminal output. I am not able to attach the JSON as its not allowed to do so. I have attached Google drive link:

I will attach the JSON too.
I have tried other ways too but nothing works.
1. This image shows 4 Cameras connected.
Terminal Output:
Two Cameras which are working on B and C ports are switched and checked on A and D port.
3. Even Tried with Arducams
