“TypeError: blob loading failed”

Anki version: 24.11
iOS version: 17.6.1
Deck: “Ultimate Spanish conjugation”

I’ve been using it for a few days, and it works fine. However, once when I was opening the deck, this error message was displayed:

When this dialog is closed, the app works normally.

So this is not a problem for me, just wanted to let you know.

It may have been a temporary error - if you find it keeps happening, are there particular steps that causes it to happen?
