Thanks Michal,

I just found the problem. I changed




And no longer see the crash!

To confirm, I put back \documentclass[12pt,chapterprefix=false]{scrbook}
And now I get the same error again right away

This document has lots of Latex code generated by Maple,
which still use very old latex font commands, and that is why I
needed to use enabledeprecatedfontcommands. The strange thing,
it only failed with tex4ht and not with lualatex.

Given that probably no one else will encounter this in the world other
than me :) I do not think it will be worth to officially make
a bug report on it and a MWE unless others think it is worth it.
