This is far from being a complete game log, but sadly enough to make me suspect this: You have a mod installed which adds custom registries and ran #mine.

I'm a bit rusty on what's included in which release, but I think this should be fixed in all latest releases of supported versions. If updating doesn't help or there is no version to update to, please let us know which version of Baritone you are using.
