No, I don't use the package from AUR, I simply do
/usr/local/opt/lmtx $ sudo ./install.sh
but I explicitly set TEXMFCACHE=$HOME/.cache/lmtx (for context suite I
set it to $HOME/.cache/context-suite).

It didn't occured to me that the problem may be with the cache, it would
be helpfull if context/luametatex will give error message, something
like "cache version mismatch" and exit.

Sometimes I live in the country,
And sometimes I live in town.
And sometimes I have a great notion,
To jump in the river and drown.
