Hello,

The issue is most likely coming from the heat map add-on, try the following

  1. Update to the latest version of Anki (your version is currently outdated), you can update through here: https://apps.ankiweb.net/
  2. After you install the new version of Anki. Go to tools in the top left ā†’ addons ā†’ get updates
