I'm getting the same issue.

In my case I'm using a newer Jetson Nano development board (2 camera ports) along with the Jetpack 4.5.1. For the camera I'm using an Arducam IMX477.

One interesting thing was I tried using an older Jetson Nano development board with the same Jetpack, but it gives me an unable to open camera error message using Python3, but is able to open the camera using Python 2.7. I'm not too worried about that one as the segmentation fault prevents using it cleanly.

I found a not perfect solution for this problem. Just rollback to jetpack 4.4.1 or older version, no errors will be throw. Maybe it's Nvidia's problem. Actually, the newer jetpack version add new platforms support, and almost no features update for Jetson nano.
