The problem persists. Here the new logfile.

1. What is the version of your Luametatex binary?

    luametatex --version
    This is LuaMetaTeX, Version 2.10.11

2. What do you get in your log-file with the following example!

    \starttext
    \show\expandeddetokenize
    \stoptext

On my system I can find the following line:

    > \expandeddetokenize=primitive \expandeddetokenize
