LuaTeX-ja doesn't play well with TeX4ht, as we don't support OTF fonts (this is what causes the fatal error --- error --- Can't find/open file `[/usr/local/texlive/2022/texmf-dist/fonts/opentype/public/haranoaji/ HaranoAjiMincho-Regular.otf].tfm'). So we need to suppress packages that tries to load OTF fonts. I've already fixed that in TeX4ht sources, but before you get the update in TeX Live, you can use the following .4ht files.
First is usepackage.4ht:

It contains instructions for packages that need special treatment, especially if they need to be handled at the moment when they load. The \Configure{PackageHooks}{luatexja-fontspec.sty}{luatexja-hooks.4ht} command will load the luatexja-hooks.4ht file before the package is used. We can block the package from further processing thanks to this file. This is how luatexja-hooks.4ht can look:

\endinput
The \:dontusepackage blocks the given package from loading. We block both luatexja and luatexja-fontspec here, as both of them cause fatal error with TeX4ht.
With this change, you should get the correct result:
