As far as Tw is concerned, there were no relevant changes to the code in
the past few weeks.

I am a bit surprised that lualatex is explicitly called through sh...
maybe you could check the definition of the lualatex typesetting tool?

Also, can you trace down where lualatex is placed and how it's defined?
On my system, it's a maze of symlinks that ultimately points to luatex.
That could potential;y also cause problems if all symlinks are resolved
and luatex is called instead of lualatex...

I would also try adding a new typesetting tool (for debugging purposes)
that just calls `env` to print the environment variables to see if $PATH
is correct.
