gnome-shell currently crashes whenever a Bluetooth headset is connected.
(In my case, a Sony WH-1000XM3.) In the system log, messages along these lines
can be found:

In addition, it appears that a fix for this is available upstream, linked in
that tracker entry. It would be nice if this fix could be made available in
Debian.
To have all the information in one place and not rely on Fedora: this is
https://gitlab.gnome.org/GNOME/libgnome-volume-control/-/merge_requests/31
which fixes
https://gitlab.gnome.org/GNOME/libgnome-volume-control/-/issues/34.
I'm surprised that you're seeing this without using pipewire from
experimental - the upstream issue report implies that it's a regression
with newer pipewire? But your bug report seems to indicate that you're
using testing/unstable pipewire?
This is a bug in a "copylib" that is not packaged separately because it
has an unstable API/ABI (libgvc), so unfortunately it needs to be fixed
in multiple places.
For gnome-shell let's use the original bug #1126514.
gnome-control-center is fixed in 1:49.4-1 so we just need to let it
migrate. Similarly phosh seems to be fixed already.
gnome-settings-daemon, gnome-flashback, phosh-mobile-settings, wf-shell
and budgie-control-center also have copies of libgvc which should be
checked and potentially updated. gnome-settings-daemon was already fixed
upstream in the main branch, but not in v49 yet.
Similar code (a fork) is present in cinnamon-desktop, although it isn't
*exactly* the same codebase. Cinnamon team: please check whether
Cinnamon also crashes when a Bluetooth headset is connected while using
Pipewire for audio; if it does, libcvc will likely need to pick up
changes from libgvc. I haven't cloned the bug for cinnamon in case it's
unaffected, I don't know how far away libcvc is forked.
