xfce4-pulseaudio-plugin: Completely unresponsive and freezes X server

Hello,

The PulseAudio panel plugin on my system does not respond to inputs and any attempt to interact with the applet or its preferences panel results in the X server being uninteractable. By that I mean that I cannot click on or use (nearly) any hotkeys to interact with the system. I must switch TTY and restart the desktop manager (systemctl restart lightdm) to fix the issue.

Oddly, the panel plugin freezes the system anywhere from 30 seconds to 5 minutes after attempting to interact with it. So far I have tried the following:

- Backed up and removed XFCE configuration for testing
- Removed PulseAudio configuration for testing
- Switched from PulseAudio to PipeWire

Nothing has made a difference. I hoped the 4.16 update might make a difference, but it hasn't. Perhaps there is a conflict somewhere, though I am struggling to find it. Could anyone please lend me their aid and terminal-level voodoo?
