While the ISBN may be valid, that mobi-asin is not even close to a valid ASIN. An ASIN is a 10 character string not a string that looks like a GUID. A sample of an ASIN would be B0BSRFPQXV.
I would also suggest removing the file you attached since I am rather certain that the line in the book reading "Copyright © 2023 by Stephen King" is a pretty good indicator that it is still in copyright.
