As per the fuller console output I included (where you can find all the details of the run as put out by ConTeXt):

This is LuaMetaTeX, Version 2.05.01 
open source     > level 1, order 1, name 'cont-yes.mkiv'
system          > 
system          > ConTeXt  ver: 2020.04.03 10:31 MKIV beta  fmt: 2020.4.7  int: english/english
system          > 
system          > 'cont-new.mkiv' loaded

If the standalone is used, it doesn’t work. If TeX Live 2019 is used, it does work.

Note, there is no ‘luatex’ command in the standalone. And I get a different output from the --version command for context:

$ context --version
mtx-context     | ConTeXt Process Management 1.03
mtx-context     |
mtx-context     | main context file: /usr/local/context-osx-64/tex/texmf-context/tex/context/base/mkiv/context.mkiv
mtx-context     | current version: 2019.07.24 11:31
mtx-context     | main context file: /usr/local/context-osx-64/tex/texmf-context/tex/context/base/mkiv/context.mkxl
mtx-context     | current version: 2020.02.17 19:36

The version differences probably from

system          > beware: some patches loaded from cont-new.mkiv

I seem to be running a beta. I seem to recall I installed that because Hans patched something, but I am uncertain. Hans?
