Error message when going into Custom Study

Hi there, the error message as shown below pops up whenever I go into Custom Study. I don’t think this is due to any add-ons as this also occurs when I start up Anki with my add-ons disabled (Starting with shift key held down). However this seems to have happened after I changed the Note Type of most of my cloze cards to the AnKingOverhaul Card type. This doesn’t seem to affect my Mobile Anki on my phone.


An error occurred. Please use Tools > Check Database to see if that fixes the problem.

Anki 2.1.44 (b2b3275f) Python 3.8.6 Qt 5.14.2 PyQt 5.14.2

Platform: Mac 10.16

Flags: frz=True ao=False sv=2

Add-ons, last update check: 2023-12-12 10:39:47

Caught exception:

Traceback (most recent call last):

File “aqt/”, line 40, in

File “aqt/”, line 65, in onRadioChange

AttributeError: ‘Scheduler’ object has no attribute ‘totalNewForCurrentDeck’

You have a fairly old version. Maybe try updating to at least version 2.1.66, and see if the problem still occurs?

But also try running Tools / Check Database, and the other troubleshooting steps.


Yes that has helped thanks!
