Error when attempting to study custom deck

Hi all,

I hope everyone’s staying safe and healthy :slight_smile:

Recently, I’ve noticed that I am unable to use Custom Decks properly. Here is what happens:

  1. I add cards into the custom deck
  2. press ‘show answer’
  3. immediately encounter the error below
  4. closing the error window and pressing ‘show answer’ brings the error back up

Error message: Error

An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.
If the issue only occurs when add-ons are enabled, please use the Tools > Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.
When you’ve discovered the add-on that is causing the problem, please report the issue on the add-on support site.

As instructed in the error message, I tried again with all add-ons disabled. Using the same steps, I encountered the following error:

I did Tools > Check Database, which did not solve the problem.

This occurs with all card types.

I appreciate any help. Thanks!

Please delete all custom study/filtered decks you have, and then make sure your AnkiDroid is up to date to prevent this from happening in the future.

Hi, thanks for looking into the issue for me.

I’m on version 2.1.22 which the Anki website lists as “a recent stable release”, with newer versions potentially not supporting certain add-ons. Do I need to be on a more recent version?

Thanks.

He told you to make sure AnkiDroid is up to date, not Anki (for desktop). As far as I know, AnkiDroid does not have addons.

My mistake, I misread that.

To be clear, I am having this issue in the windows desktop Anki client. I recently updated Ankidroid and my custom deck has been empty. Custom decks have always worked fine in Ankidroid. The error in the windows client persists. The error message does look slightly different, but I’m not sure if this is significant:

Quick update: I erroneously thought emptying a custom deck was the same as deleting it. I actually deleted the empty custom deck that I had and the problem is solved. Thank you both very much for your wisdom
