SUMMARY
On login, plasma-login-manager's kwin process exits with an exit-code=15, so systemd considers the service failed:

2月 17 11:05:33 laptop-jin-mi systemd[914]: plasma-login-kwin_wayland.service: Main process exited, code=exited, status=15/n/a
2月 17 11:05:33 laptop-jin-mi systemd[914]: plasma-login-kwin_wayland.service: Failed with result 'exit-code'.
2月 17 11:05:33 laptop-jin-mi systemd[914]: Stopped KDE Window Manager (Login Manager Version).
2月 17 11:05:33 laptop-jin-mi systemd[914]: plasma-login-kwin_wayland.service: Consumed 1.445s CPU time over 14.783s wall clock time, 301M memory peak.

I don't know if this is intended behavior. But it seems suspicious to have a unit failing in the boot process.
