There are two sets of bindings for GObject - the old ones which were
manually written and the new ones which are introspection based. You
can't mix both in the same process or bad stuff happens.

Your 'import gio' is pulling in the old bindings which clashes with
the introspection based ones pulled in by libosinfo. Change your
change to

  from gi.repository import Libosinfo as osinfo
  from gi.repository import Gio

Then you can access  Gio.Cancellable
