Unable to sync anki - Traceback error

Anki Help

Hello,
I just noticed this problem yesterday - every time I sync Anki, I get this error:
Syncing failed:
Traceback (most recent call last):
File “aqt/sync.py”, line 429, in _sync
File “aqt/sync.py”, line 409, in _abortingSync
File “anki/sync.py”, line 136, in sync
File “anki/sync.py”, line 218, in sanityCheck

File “anki/schedv2.py”, line 213, in _walkingCount
File “anki/decks.py”, line 612, in parents
KeyError: ‘AnKing::Zanki Step Decks::Zanki Neurology’

I have tried “Check Data Base”, restarting my computer, downloading the new Anki Version 2.1.26 but am not sure what else to do. Any help would be greatly appreciated!!!

Does the problem persist if you update to Anki 2.1.29?

No but I had to just import a backup of my Anki deck and it worked fine and the error went away. Thanks!
