indeed with the downgrade of libwireplumber-0.5-0_0.5.12-3_amd64.deb
and wireplumber_0.5.12-3_amd64.deb from snapshot.debian.org and
restarting wireplumber user session, the issue is fixed. I can switch
input to bluetooth HSP/HFP back and forth in gnome-control-center
without issue with pipewire 1.4.9-1+b1 from forky, 1.4.10-1 from
unstable and 1.5.84-1+b2 from rc-buggy.

But note that rc-buggy pipewire 1.5.84-1+b2 does not work for bluetooth
(but produces no crashes, only a hang for a few seconds). Be it audio
out or in A2DP or HSP/HFP whatever the codec selected.
While for pipewire 1.4.9 and 1.4.10 both works (even if there are some
minor issues, which were the cause of my trying rc-buggy pipewire but I
can live with these for now).

Well at times the profile felt back to A2DP and no HFP for input, then
no crash until I switched to HFP.
Not tried but likely would have allowed me to start gnome-shell until I
attempted to switch back to HFP.

Thanks a lot, I did not though of wireplumber as a culprit.
