Hey @Jason_A,
Thanks for going through all the steps (and even more than once!). I only wish the result would have been what we were all hoping for: a restored database, so all your playlists, tags, favorites, play history, settings and so on will be just as before.
Do you have another backup (older) you could restore? I ask because, other than that, as much as it pains me to say, starting fresh is the only other alternative…
We created this post explaining things in more detail:

I couldn’t be more sorry this is the case. Our team is going through the same thing and we feel your pain… some of our databases are not restoring either
