Daemon Helper Service Lockup

[alkaris2]

Introduction
Encountered a bug where Eruption Daemon Service locks up entirely with no keyboard input and unplugging and reconnecting keyboard does not recover input response when reconnected to the system. It appears to enter "dead" state on keyboard input and returns error that the device went away when it's still connected and in use

Please describe the bug
This bug appears to be in relation with the helper service for Eruption the eruption-hotplug-helper.service which incorrectly deactivates itself.

To Reproduce
Unsure how to reproduce, but when it bugged out no keyboard inputs were working. I had to remote into the PC via SSH to restart the daemon service for Eruption to restore keyboard input.
