I recently switched from MATE to Gnome I experience the same problem.
I have found that I can start gnome-control-center if I set the environment variable CLUTTER_BACKEND to wayland. You can start in in your shell like so:

CLUTTER_BACKEND=wayland gnome-control-center

If I check my current environment for clutter environment variables I see:

$set | grep -i clutter
CLUTTER_BACKEND=x11
CLUTTER_IM_MODULE=xim

None of those are set in any of my dot files in my home, the culprit appears to be:

X11/Xsession.d/99mate-environment: export CLUTTER_BACKEND=x11

I have had a working 18.4 system for a few months.
Today a software update ran, which I allowed like I always do.
Then went to play OpenRA and it would not run well enough to play.
So I was going to settings to check the display settings.
Only to be presented with a Select User screen, enter password, then back to Desktop.

I had to search and find how to use terminal and uninstall and reinstall.
I uninstalled gnome-control-center
And re-installed gnome-control-center
Rebooted and still same thing.
I tried opening the gnome-control-center using terminal and same thing.
Select user, enter password, back to desktop.

So far none of the steps I can find will allow me into the settings.
