Luigi, shouldn't on the face of it an assert always be considered an issue
in the code raising the assert?
Marcel helped narrow this down to a plain tex example


which produces

This is LuaTeX, Version 1.12.0 (TeX Live 2020)
 restricted system commands enabled.
(./as.texassertion "is_simple_character(wordstart)" failed: file
web2c/luatexdir/lang/texlang.c", line 986, function: hnj_hyphenation
Aborted (core dumped)

I get the same in luatex 1.11.2  but it works in luatex 1.07.0


So I think it is definitely a luatex issue not in the tex or Lua code here.
