I also now tried with  ArchLinux Plasma, same missing 'wl_shell' segfault.  I found some tip about having to enable a compositor?

Code:

export $(dbus-launch)
kwin_wayland --xwayland

but this also fails, but sounds like maybe wayland is already running, very confusing:

Code:

No backend specified through command line argument, trying auto resolution
unable to lock lockfile /run/user/1000/wayland-0.lock, maybe another compositor is running
kwin_core: Failed to activate /org/freedesktop/login1/session/_33 session. Maybe another compositor is running?
kwin_wayland_drm: failed to open drm device at "/dev/dri/card0"
kwin_wayland_drm: failed to open drm device at "/dev/dri/card1"
kwin_wayland_drm: No suitable DRM devices have been found
