For what's worth, running your example in TeXShop on the Mac (with engine ConTeXt.engine, namely "context --autogenerate --luatex --synctex=1 "$1""):

- In TeX Live 2025, no problem, output is produced.

- In TeX Live 2026, I get in the console

mtxrun          | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua'

Looking further:

- With TeX Live 2025:

% kpsewhich mtx-context.lua
/usr/local/texlive/2025/texmf-dist/scripts/context/lua/mtx-context.lua

% mtxrun --locate  mtx-context.lua
/usr/local/texlive/2025/texmf-dist/scripts/context/lua/mtx-context.lua

- With TeX Live 2026:

% kpsewhich mtx-context.lua
/usr/local/texlive/2026/texmf-dist/scripts/context/lua/mtx-context.lua

% mtxrun --locate  mtx-context.lua


Namely, blank line of output for the latter: mtxrun doesn't find mtx-context.lua in TL 2026. I tried adding --usekpse or --forcekpse, no luck, mtx-context.lua still isn't found.
