It's a matter of which python you use. The one that understands msys
paths is msys/python. The mingw64 packages are normally pure native
windows and so don't understand msys paths. I know it's confusing :-(
# /usr/bin/python -c "import os; p = '/usr/lib/perl5/core_perl/CORE';
print(f'does {p} exist:', os.path.exists(p))"
does /usr/lib/perl5/core_perl/CORE exist: True
