Cannot Enable the Addon

When I try to enable this addon after downloading it from the Godot Asset Library, I get this error message:

Hard to say why you're having so many issues with the plugin, since we don't have much information on your project setup and structure, your OS, etc...

That said, try removing the entire plugin folder and installing from the release download here on GitHub by extracting the "addons" folder into your project folder.
