I believe this should be fixed in the beta version (3.5.99), available as Ubuntu packages here:

Title:
  segfault on KDE Plasma wayland

Status in Cairo-Dock Core:
  Fix Committed

Bug description:
  Downstream bug: https://bugzilla.redhat.com/show_bug.cgi?id=2000812

  On Fedora 34 KDE Plasma wayland session, using cairo-dock
  https://github.com/Cairo-Dock/cairo-dock-
  core/commit/6c569e67a2a366e7634224a0133ede51755629cb ,

  `$ cairo-dock -c`

  causes segfault at starup as atatched. This does not occur with GNOME
  + wayland - so apparently this is related to wayland implementation on
  KDE plasma.

  So what is happening here is that cairo-dock calls
  wl_output_add_listener(), expecting that "geometry" information is to
  be returned first before "mode" information is gained. GNOME + wayland
  returns the information in this order, but KDE plasma + wayland
  returns in the opposite order.

  Currently I don't know this behavior is allowed or not. But perhaps cairo-dock side can workaround this issue by allocating g_desktopGeometry.pScreens on _output_mode_cb() when the pointer is still NULL, perhaps? (at least this workaround seems to work for me).
