Hello,

  1. You are not on the latest version of Anki. Download it here: https://apps.ankiweb.net/. After downloading, simply run the downloaded file to update your application.

  2. It looks like your collection is corrupted. You will need to restore it from a recent backup made before the issue started.
    Please see this tutorial for step-by-step instructions on how to do that: How to Restore from Backup
