CSI IMX219-160 Camera 160 is not working on Jetson Xavier nx

We are having Jetson nano 2GB and Jetson Xavier nx.
We purchased two CSI IMX219-160 Camera 160 FOV. Both the cameras were working fine on both the Jetson Modules. But now only one camera is working fine on both the Jetson Modules and the second camera is not working on any module. It was working yesterday but now not working. There is no physical hardware damage but still not working. Please tell us how to make it work now.
