Anki2Memrise Addon Not Working

Hi All,
I am new to Anki and just downloaded the Memrise extension but have been receiving an error message when I try to load my course from Memrise (see below):

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.
When you’ve discovered the add-on that is causing the problem, please report the issue on the add-on support site.
Debug info:
Anki 2.1.49 (dc80804a) Python 3.8.6 Qt 5.14.2 PyQt 5.14.2
Platform: Windows 10

course.title = sanitizeName(courseData[“session”][“course”][“name”], “Course”)
TypeError: ‘NoneType’ object is not subscriptable

At this stage, it is the only add-on I have.
Any assistance would be greatly appreciated!
Many thanks in advance!
