You're probably going to have a better time here reporting this to the
Git for Windows folks at https://github.com/git-for-windows/git.

When you report this, you'll need to mention which file system you're
using on your NAS, since it's probably related here.  You may also be
running into filename length problems and you could try turning on long
path support.

Finally, something else you could try is to see if some other process is
using these files and if so, kill it.
