Hello,

Let’s try this first:

Your Anki is not up to date (2.1.63), you can download the latest version (25.02.5) from https://apps.ankiweb.net/. Just run the downloaded file, and Anki will update automatically.

Then update the AnkiHub add-on:
Go to Tools > Add-ons > Check for Updates. Restart Anki after that.

Please let us know if the issue occurs again!
