Settings not opening on Ubuntu 19.10

I recently upgraded to Ubuntu 19.10, but I'm not able to open Settings.

killall gnome-control-center

gives

gnome-control-center: no process found

And also my laptop is hanging many times, I had to press the power button every time to restart.

gnome-control-center --verbose

gives

Segmentation fault (core dumped)

but gnome-control-center --version gives gnome-control-center 3.34.1

Solution 1:

It also happened to me when I tried to open Devices section.

Someone pointed out that you can reset the last panel using a terminal:

gsettings set org.gnome.ControlCenter last-panel ''

It does not solve the Devices section issue.
