AnkiApp import failure

Hey everyone
I want to import a deck of a friend to my Anki App on Mac OS High Sierra but every time I try I get an email saying there was an error when importing your APKG file. And I get the error message I attached. I am new to Anki so I have no clue at all what to do and I would be very grateful for help :slight_smile:
