Is it telling us that something is wrong or missing from the theory of
quantum mechanics? Is there something wrong with general relativity?
Or is the information not actually lost in the first place?!

Most of your questions are answered in the book "At Home in the Universe"

universe via decoherence, which creates more information where there was
less before.
