OMM (DO Demeter) Deck - Problem with Importing Images

I recently subscribed to the OMM Deck by @antibrotease and I am having issues importing the media for the deck. I downloaded the zip file to an external hard drive, but get the following error message whenever I try to import:

After deleting the problematic image from the folder, I continue to get the same error for other images.

I then tried using the mega link instead. When I click “check URL”, AnkiHub breaks and I get a different error message* (pasted at the end of this post because it’s long).

Am I doing something wrong, or is there a problem with the media for this deck?

*Error message:

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 to the add-on author.
