Fails with error: TypeError: cannot unpack non-iterable NoneType object

The tool fails soon after starting. Seems that cur.fetchone() in decrypt_with_manifest is returning None.

The error message is:

Traceback (most recent call last):

I am running the tool with rtx-installed python on the latest version of MacOS. The provided error message was produced using python 3.9.16, but I've also tried with python 3.11.2 with the same result.

Also I'm running the tool from my home directory, with the full path to backup directory as a parameter (I've verified that I have the Manifest.db and Manifest.plist, among other things, within the backup directory). The backup is encrypted and I've tried with both interactively providing the password as well as providing it as an argument - no changes here either.
