Advanced mpv player

I am running into an issue. I am using anki version

Version 2.1.35 (84dcaa86)
Python 3.8.0 Qt 5.14.2 PyQt 5.14.2

and have tried to add on the plugin but i keep getting this error:

An add-on you installed failed to load. If problems persist, please go to the Tools>Add-ons menu, and disable or delete the add-on.

When loading ‘⁨Advanced MPV Player⁩’:
⁨Traceback (most recent call last):

av_player.players[0] = MpvManager2(
TypeError: init() missing 1 required positional argument: ‘media_folder’

Can maybe you explain to me how to fix this ??? Thank you!
