Error on macOS

[101Dude]

This is the only extension I have installed on a new and first install of Anki.

Error
An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.
If the issue only occurs when add-ons are enabled, please use the Tools > Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.

Hey
I'm sorry my life was really busy when you opened the issue. Missed the notification, I guess.

The add-on works on the latest version of Anki.
Do you still have any issue with the add-on?
