The internal metadata shows it to be in KF8 format, created using calibre version 4.17.0 on October 17, 2022. Looking at the file shows the typical minor structural errors that calibre produces for Kindle formats. I will look into this further to see whether I can determine what specifically in that file leads to this error.

I found that renaming the file from pg38497-images-kf8.mobi to pg38497-images-kf8.azw3 allows my Kindle to open the book without error.

I then opened it with calibre's editor and clicked on the bug icon. It came up with quite a few errors. Most of the errors were "The linked resource '1256390145133242086_cover.jpg' does not exist" in the html files plus an Invalid id:73721-2dc923c5fc2b4a448ba58a66306d939e in part0041.html. That and an unused 00004.jpeg image which seemed to be a thumbnail for the cover image.

I clicked on the Try to correct all fixable errors automatically option and it correct all the errors except the 00004.jpeg file not being referenced error. After this I sent the fixed ebook to a PW4 with frirmware 5.15.1 and it opened happily. Though I'm not sure about a table of contents with overlength chapter titles shown in narrow columns.

Edit: attached a screenshot of one of the pages around chapter XI.
Sounds like that uploader and maybe Project Gutenberg in general has serious toolchain/workflow issues.
