How to Restart Gnome Shell from Command Line?

I would like to implement a keyboard shortcut to restart gnome-shell whenever this one crashes (some bugs aren't currently fixed just yet). For this I would need a command line to restart the shell.

The Alt+F2 and restart command won't work when the shell is crashed because the prompt is implemented in the shell.

Hence, how to restart the gnome-shell from command line?

GNOME Shell 3.30.1 on Ubuntu 18.10

The command to replace gnome-shell would be sending a SIGQUIT signal to it with:

killall -3 gnome-shell

or:

killall -SIGQUIT gnome-shell

As of GNOME Shell 3.30.1 on Ubuntu 18.10, the solution below no longer works, and will kick the user to the login screen, losing all of their work.
