I have the same issue here, when I select Power panel, The control center crash immediately, and keep crashing when trying to open it again.

Although I found a temporary solution to open the control center: "gsettings reset org.gnome.ControlCenter last-panel"

This command will reset the last visited panel. But the problem remains, no one can open the power panel.

Same here and when i use gsettings reset org.gnome.ControlCenter last-panel it lets me bring up setting and use any of it but power settings it just crashes

Have same issue with the Plasma here. Sometimes the control center crash immediately

I have the same issue. If I try to enter on the battery menu, the Control Center crash, but after this, if I try to enter on Wireless settings, Internet settings and any other options, the same issue occurs, and this all since yesterday.

Also seeing the same bug. A good explanation of the cause may be found here:

https://superuser.com/questions/1681596/why-is-gnome-control-center-trying-to-access-a-gsettings-key-that-doesnt-exist

Yeah that's right, gnome-settings-daemon is still 3.38.2-1, gnome-control-center and gsettings-desktop-schemas are both 41.0-1

The thing is, if you force the upgrade of gnome-settings-daemon to 41.0-2 with kali-dev or unstable repo, it will force the upgrade of gnome-shell and mutter to 41.0-1.

Something I never want to, Gnome 40/41 is too buggy. I will try to downgrade both gnome-control-center and gsettings-desktop-schemas to 3.38 in that case.

Even after reinstalling using live instead of offline does the same thing

I think you should log-out or kill X first before, it's not effective immediately.

With kali live, it's nearly impossible to do this, unless you have a persistent live partition

Ok, so I did it!!! the power panel can be opened normally with eithers operations:

Either you upgrade to gnome 40.4 with kali-dev repo: "apt install -t kali-dev mutter gdm3 gnome-shell gnome-control-center gsettings-desktop-schemas gnome-desktop3-data gnome-session"
OR
You downgrade to gnome 3.38.6 with kali-last-snapshot repo: "apt install --allow-downgrades {mutter,gdm3,gnome-shell,gnome-control-center,gsettings-desktop-schemas,gnome-desktop3-data,gnome-session}/kali-last-snapshot"

I made both tests, and it's WORKING!!!

Same here for the last week. After upgrading kali 2021.3 I'm no longer able to access my settings. I've uninstalled and reinstalled but after upgrade nothing happens.
I finally reinstalled....set my power settings before updating but soon after, now I'm back to square one. Not able to access my settings panel.

Waiting for a patch in the next update until further notice.

I was unable to get j_jito's upgrade/downgrade options to work. Not that this matters, though. I'm using Kali Rolling and want to be careful about upgrading by going to the kali-dev repository. On the other side of the coin, I'm not too keen on downgrading what I've got, either (other than the power panel, it seems to be working well).

Looks like I'm stuck waiting for a patch via normal channels!

I tried upgrading and down grading and it gave me errors because of updated packages being newer then ones being installed there where 2 of them i removed the first package and all i got was a curser i rebooted and it worked fine

After updating this morning 10/18/21 I'm now able to access the settings panel without any issues.

Thank you

It should be working now, Kali team just pushed gnome-shell 40.5 to Kali-Rolling channel

This is now fixed with the update for gnome 40
If it still gives you any issue feel free to reopen this bug report.
