So I've tried to check it out manually and it turned out that

You can inspect what was checked out with 'git status'
and retry the checkout with 'git checkout -f HEAD'

I guess it could be somehow addressed by allowing for long paths, see https://stackoverflow.com/questions/22575662/filename-too-long-in-git-for-windows or maybe filenames could be shortened a bit.

I do not have any windows system to test or patch. Would you be willing to help out with a PR?

I'm really sorry, but I don't have enough time to dig into this topic at the moment.
