You will need to update your addon installation to the latest version.

Once up to date, you will be good to go. Unfortunately older versions of the addon can't work with an ever changing blender so updates are required. I hope that helps and reduces confusion. Blender changes over time and this requires updating.
Thank you for your review and shared opinions.
