PYAPP_DISTRIBUTION_SOURCE set to mingw distribution

export PYAPP_DISTRIBUTION_EMBED='1'
export PYAPP_DISTRIBUTION_PATH_PREFIX='ucrt64\bin'
export PYAPP_DISTRIBUTION_SITE_PACKAGES_PATH='ucrt64\lib\python3.12\site-packages'

When I try to build my app with the variables above , the command pyapp.exe self python fails with

error: Command '['C:/Users/ME/AppData/Local/pyapp/data/aicam/10914280944476335129/1.0/bin/python.exe', '-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

It seems that the distribution is not being unpacked on that path?

It seems the python distribution is installed in \AppData\Local\pyapp\cache\distributions\_10914280944476335129 but at runtime the executable looks for it in /AppData/Local/pyapp/data/aicam/10914280944476335129/1.0/bin/. Does someone has any suggestion?
