If you manually take over management of the process from the system then it's on you to keep that working.

You probably want
systemctl --user restart plasma-plasmashell

To be fair, nowhere across whole KDE people mention implications of that as `plasmashell --replace` is basically a thing everyone suggests doing when you need to replace plasma for some reason.
