Jetson-io.py doesn't work for Jetson Xavier NX

Hi.
While trying to enable pwm pins through jetson-io.py, I realized that it doesn’t work.
I tried "sudo /opt/nvidia/jetson-io/jetson-io.py "
it shows gray for a second and it automatically disappear.
I’m using Jetson Xavier NX.

my tegra release is as below
R35 (release), REVISION: 2.1, GCID: 32413640, BOARD: t186ref, EABI: aarch64

and I’m using HDMI port for the display.

Thank you in advance!
