Linux - OpenRGBEffectsPlugin not showing as installed on Ubuntu/POP_OS

After installing OpenRGBEffectsPlugin on both Ubuntu and (Ubuntu based) POP_OS, it does not show up in the OpenRGB GUI. This problem exists when using either .deb or Appimage. It is being properly installed to the ~/.config/OpenRGB/plugins directory, just not populating in OpenRGB.

It works flawlessly under Arch and Manjaro (git installed from AUR).

All operating systems were freshly installed/updated on bare metal.
