I was able to reproduce this bug on Ubuntu 22.04 + telegram-desktop
4.14.15 rev 5557 (installed with snap), apport 2.20.11-0ubuntu82.5

$ cat /var/log/apport.log
ERROR: apport (pid 47286) Tue Feb 13 21:54:27 2024: host pid 44216 crashed in a separate mount namespace, ignoring

  systemd ProtectSystem/mount namespace makes apport fail (impact most
  of our default system services)

Bug description:
  [Impact]
  apport is not creating crash files for multiple system services that use ProtectSystem since Ubuntu 20.04 LTS.

  [Test Case]
  On an Ubuntu desktop system perform the following step
  1) sudo pkill -11 upowerd

  With the current version of apport there will not be a crash file for
  upowerd in /var/crash/. With the version of apport in -proposed there
  will be a crash file for upowerd in /var/crash/.

  [Regression Potential]
  In the event that the changes to /usr/share/apport/apport are bad then apport itself would crash thereby preventing us from getting any crash reports. So in addition to killing upowerd we should also test a regular application like xeyes.

  [Original Description]
  bluetoothd never leaves dumps/crash files when it crashes

  And it seems this is true for everyone. Only supplementary binaries' crash reports are shown:
