I’m looking for a solution to a bug which only started recently. I have the latest version of anki desktop. When I am trying to go back to cards I made last year, I receive an error every time I try to lapse a review card, but was fine if I answered anything apart from “again”. The error initially said it was related to add-ons, but after I disabled them the problem persisted. I checked the database, restarted my computer and the problem still persists. I can still do the cards on my Ipad, so it doesn’t seem to be an issue with the card itself. I’ve included the error message below, does anyone know how to fix this?
An error occurred. Please use Tools > Check Database to see if that fixes the problem.
