Yes I noted it doesn't answer the "hard" problem explicitly in both of my replies here on this thread. Indeed, the very reason it is called the "hard" problem is b/c it very well seems perhaps unsolvable (though this is certainly debatable, but this is the very etymology of the term).
Your actual stated questions (why am I me and not someone else, etc) are in no way part of the "hard" problem's formulation, and are indeed easily answered by materialism as I noted.

Perhaps take a look at the wiki article on the hard problem: https://www.wikiwand.com/en/Hard_problem_of_consciousness
