2 years ago Recent update to Tcolobox resulted in fatal error in TeX4ht, but fix for this issue should already be available in TeX Live. I can compile your test file without error, but with a DOM warning. Also the title is missing. The following version of tcolorbox.4ht should fix these issues:

Compiling this document with "pdflatex" works fine, but compiling with "make4ht" (make4ht testmybox.tex -l -u -s -d dist "mathml") produces an error.
I don't understand this error since, some time ago, similar code was compiling correctly.
