Somehow some msys2 libraries conflict with git's cygwin version of tar. I guess the fix would be to find a way to update the PATH to exclude msys2 again after our work is done and before the caching post steps run...

@RealCLanger Oh, thanks for the analysis! I believe it should be possible to update the PATH; it might require a bit of trickery/ugliness, as so many other things in this yaml "programming language", but it can most likely be done.
