Cards available in browse but disappear when trying to study

Hey, Im having some problems with my Anki.
When i go to browse decks all the cards are there, however, when i go to study these cards they disappear. If i then click on study, even though there is no cards showing in the deck the message below appears.

If someone could assist me that would be greatly appreciated!!
Thanks.

This seems to cause the error. You should update it to either v2 or v3. As you’re running Anki 2.1.52, you could open Preferences -> Scheduling and enable v3 there.

I guess this error could be a little more user-friendly, that is, instead of show a python traceback, it could just show a pop-up saying something similar to
