I was trying to do my work on Blender 4.0. But I faced difficulties while adding the addon. After reading the issues, I downgraded to version 3.4 and successfully add the addon. But after completing my word I got the error while exporting.

Versions of blender from 3.4 onwards are currently not supported. We support 3.3 LTS and will soon support 3.6 LTS as well. Please try again on Blender 3.3 and let us know if the issue persists.

This should now be fixed with the latest release of the add-on. Please upgrade and re-open this issue if the problem persists.
