How to shutdown N10/Debian

I have N10 with debian image rockpin10a_debian_buster_xfce4_arm64_20210125_2013-gpt.img.gz
I am failing to do shutdown -h now or using XFCE4 UI
In both cases N10 restarts. So there is no safe way to turn it off.

Is there any solution to safely turn off N10/Debian?

how about " systemctl poweroff " ?

sry for being late.
It still reboots
