[JetPack 4.3 - L4T R32.3.1 ] Whole system goes dead when connecting VPN

Dear experts,

I have just setup my Jetson Nano with the latest JetPack 4.3. And I am trying to connect a VPN. But after I click connect after input the password in the VPN Authentication popup, after couple of seconds, the whole system goes dead. No clicks or keystrokes can work. Even the remote SSH session is frozen as well. Not sure how to fix that…
I also copy the syslog below. The deadness happened at around 19:59 and then after couple of minutes’ freezing time, I re-pluged the power adapter.

Much appreciated for your kind help.

Could you try another desktop? Just for a quick confirm.

sudo apt install xfce4

And try again with the VPN connection to see what happened.
