Here's what I suspect the problem is:

Since you're on Windows, the FULLPATH above probably includes the drive
letter followed by a colon.  We also use colon as field separator
character, so the one following the drive letter is misinterpreted as
starting a new field.  Earlier this year, we've made code changes to
strip any colons from that field.  However, the john-1.9.0-jumbo-1
release is from 2019, and thus does not include that change yet.

You can avoid this problem in one of three ways:

1. Invoke dmg2john on a relative rather than absolute path - e.g., "cd"
to the directory containing the sparsebundle and invoke dmg2john on just
the sparsebundle's name, omitting the path.

2. Edit the "hash" string you've already obtained to remove the colon
from the FULLPATH (e.g., replace it with a space).

3. Use our latest code from the GitHub repo.  There's a recent Windows
build of it available via the "Download Windows Build" badge at the top
of as displayed here:

With option 3, you'll probably want to use the newer versions of both
dmg2john and john.

I hope this helps, and please let us all know which option(s) you ended
up trying and whether it worked or not.
