Export not working

I have been using Anki for over a year but sometime last month, I suddenly noticed I am unable to export Anki decks to a .apkg file anymore. I find this a useful way to create a backup file but am now unable to do so.
I have tried ‘Tools > Check Database’ but that didn’t help.

Here is the error report:

anki.errors.TemplateError: Card template ⁨1⁩ in notetype ‘⁨Cloze (overlapping)-b3cf6⁩’ has a problem.
See the preview for more information.

I would appreciate any help. Thanks!

What does the preview for Card template ⁨1⁩ in notetype ‘⁨Cloze (overlapping) say?


I am not sure how to screenshot the preview, but I have transferred all the cloze (overlapping) cards to a new profile using a new anki account, and managed to export all the remaining cards. This has made me feel a lot more secure. Thanks for your help!
