Roon Plugin uninstall issue

Volumio Information

Volumio Version: latest beta
Hardware: Raspberry pi4
DAC: Dragonfly Black 1.5

when I try to uninstall the roon plug in , I get this error, what do I need to do? I wrote Volumio support and they said I need talk to the plugin author… How do I think the plug author

Plugin uninstall failed

An error occurred while uninstalling the plugin: Error: Command failed: /usr/bin/sudo /bin/systemctl stop roonbridge.service Failed to stop roonbridge.service: Unit roonbridge.service not loaded.

I had that error when the plugin was not installed completely. Can you re-install it? And the deinstall?

I can’t re-install it. when I click uninstall, I get that error. Totally stuck.
Tried rebooting, nothing, still can’t remove it. How the heck am I suppose to find the plugin author?!

I remember having had a similar issue. I reburnt a Volumio instance and started from scratch
