This is probably "caused" by "systemd dbus activation".

Git commit 25e84f3f6ac54097d9c021705dc18b187352fa02 by David Edmundson. Committed on 18/12/2020 at 17:29. Pushed by davidedmundson into branch 'master'. Avoid autostarting kglobalaccel when shutting down Order of our service teardown is somewhat undefined. kglobalaccel5 can be closed before plasmashell. On plasma exit we call setInactive/unregister on various kglobalaccel actions and accidentally spawn kglobalaccel again. If kglobalaccel is already closed, our actions aren't registered. There is no point waking it up to try and remove an action. Use of the setAutoStartService flag was chosen over checking if the kglobalaccel service is still registered as that is still racey. This was always slightly broken, but changes in the ecosystem means the effect has worsened.

That seems like a slightly different issue - kglobalaccel exits with 1, so systemd tries to restart it. Question is why it exits with 1.
