So much of the stuff in the mathematical-this and physics-that of conscious experience is just crap because there is very little understanding of biological consciousness and what it is and where we can find it, and where we cannot. These start with assumptions of what consciousness is and then go on to mathematize these non-validated assumptions. (Integrated Information Theory) IIT is the most popular among these. https://scottaaronson.blog/?p=1799 -- this article captures well why IIT, and many like it, are bad models of consciousness.
Anil Seth's Being You is a recent one that does a good job of summarizing the most popular theories in consciousness. https://www.goodreads.com/book/show/53036979-being-you
