That's too old, since you've upgraded Armory to 0.96.5, you may update Bitcoin Core to v27.0 though it should still work.
You can download the older releases from here:

When goatpig instructed you to delete the databases folder,
Did you delete the literal "
databases" folder inside armory folder or the "
armory" folder itself?
Because the latter will get your wallet deleted, in this case, you can just restore it back since you have your backup.
