It does not matter whether I give it a full path. I only have one hard
disk and in both cases the outcome is the same: it fails with no message
in "Error Output".

If you look at the code, I had to set PATH to point to
c:/msys64/ucrt64/bin, including the full set of files of the UCRT
version of Mingw into the path, at least temporarily. Adding this path
to the global path of Windows is not recommended, as one has instead
different shells or different scripts to activate those
sub-distributions.

Other software packages such as pdf-tools take care of this by
installing a minimal MINGW distribution during the building of the
software. Maybe that's something to consider.

Best,
