I've got the same configuration and I'm getting the same results:

   $ context --luatex test.tex
   mtx-context     | redirect luametatex -> luatex: luatex --luaonly "/opt/context/tex/texmf-linux-64/bin/mtxrun.lua" --script mtx-context --luatex test.tex --redirected
   mtxrun          | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua'
   
   $ luatex '\relax'
   warning: /opt/context/tex/texmf/web2c/texmf.cnf:49: (kpathsea) No cnf value on line: OSFONTDIR =.
   This is LuaTeX, Version 1.15.1 (TeX Live 2023/dev) 
    system commands enabled.
   
   kpathsea: Running mktexfmt luatex.fmt
   mktexfmt: No such file or directory
   I can't find the format file `luatex.fmt'!
   
   $ luatex -ini '\end'

   No pages of output.

LuaMetaTeX works fine though.

Thanks,
