This looks like some sort of problem writing to disk to me.  Where are
you storing your Git repositories?  Is it on a regular NTFS disk, or a
file share, or something more esorteric?  And does that drive have
plenty of free space?

Can you please provide the cygcheck output per
https://cygwin.com/problems.html?

If neither of these points at an obvious problem, I expect the next step
will be either (a) looking at Cygwin strace output to get a more
detailed view of what's happening when things go wrong, or (b) having
you build and run the full Git test suite with a view to using that to
narrow down what steps are going wrong.
