I haven't updated this codebase in three years now so it's probably Authy has changed its on-disk format. You'll have to see what they changed.

PEBKAC: not all my totps wer unlocked (red padlock) in the app thats why decryptedSeed was empty in the xml and had your code fail. I have unlocked all totps and reran the code successfully.

Good night
