Hello,

Follow these steps to solve the issue:

Update your Anki. You can download it here: https://apps.ankiweb.net/. After downloading, simply run the downloaded file to update your application.

Update your AnkiHub add-on:

  1. On your Anki main screen, go to Tools > Add-ons > Check for Updates.
  2. After the update is complete, please restart Anki.
  1. Check Database: Open Anki, go to the top menu, and select Tools > Check Database. This is Anki’s built-in maintenance utility. It will scan for orphaned notes, rebuild broken relationships, and clean up cards attached to missing note types.
  2. Empty Cards: Run Tools > Empty Cards to clear out any blank cards that might have been generated by the missing data.
  3. Restart and Sync: Close Anki, reopen it, and manually trigger the AnkiHub sync again.
