cannot open control center if one panel is erroneous
if there is one section that causes the process to crash, it's not possible to use any section of settings afterwards, because it tries to reopen the erroneous panel before the user could switch to another.
workaround:
use overview search, quick settings, or cli e.g. gnome-control-center sound
to open another section of settings, have it crash trying to open two panels at once (if the cpu is unfortunately fast enough), then start it again
feature request:
if the process had exited abnormally the last time, open a panel other than the saved one
