Hello,

This error appears to be caused by the note type “Basic (AnkiCollab) (Mastering Radiology / drradiology)-7d4ab” from the Mastering Radiology deck (Sign In).

If you don’t use this note type, you can delete it by going to Tools > Manage Note Types on your Anki main screen.

If you do use this deck or note type, I recommend contacting the deck author to resolve the issue. Since this is not an official AnKing deck, our ability to assist is limited.

Let us know if you need help with anything else. :blush:
