After install in addons, there's no dependencies pacakge button appears about blendarmocap

[haker1023]

I use blender 2.93 and pip upgraded, open-cv-python , mediapip installed , python is which blender's version

ValueError: register_class(...): already registered as a subclass 'PREFERENCES_OT_install_dependencies_button'

I can imagine there is an add-on using the same name for the class. Can you use a blank blender version and give the installation a try? If that's the issue I'll just have to change the name to something more unique..

I've abstracted the name a little bit more, let me know if that fixes your issue.
