Syncing leading to error with updating Anking Step1 and Step2 Decks

Before the error happened, I was…
I clicked “Sync” and a window popped up that Anking notes were updating for Step 1 and Step 2 decks. Following the uploading of a ton of notes, it crashed and left me with the error report down below.

Sentry link (for developers)

@lkh001 Go to AnkiHub > Deck Management and toggle this option on or off. Simply changing this option to any state should fix the issue.

@jakub.f any idea about this?

Hi, thanks for your help.

I’m struggling to find this window. To clarify, should I be able to get to this from the topbar in Anki?

Yes, it’s in the top menu of the main window.
