Can you try restarting Blender and enabling it again?

hey not sure if they got back to you but I had the same error, restarted blender and then got the same error when attempting to enable. Only earlier versions install but eventually break as well.
OS: Windows 10
Blender Version: 3.1.1

Thank you for the add-on btw!
