This bug was fixed in the package gnome-shell - 42~beta-1ubuntu3

---------------
gnome-shell (42~beta-1ubuntu3) jammy; urgency=medium

  * debian/patches: Adapt the theme-switcher code to keep gtk and shell in sync
    We only used dark theme for the shell before while now it will match the
    rest of the system.
  * debian/patch: Fix a crash on shadow computation (LP: #1947315)

Although zero crashes (of the same stack trace) in releases after Jammy suggests this should stay closed.
