anki.errors.TemplateError: Card template ⁨2⁩ in notetype ‘⁨Basic (and reversed card)-83c79⁩’ has a problem.
The front side is identical to card template ⁨1⁩.

Recently, some checks have been added to save users from some common mistakes. One of these checks is to ensure that you don’t accidentally create multiple cards with identical front sides. As the message says:

Since the notetype is called ‘⁨Basic (and reversed card)…’, you probably want the front side of the second template to be the same as the back side of the first template, don’t you?
