I am using Github Windows 1.0.38.1 and when I click the \'Sync\' button after committing, I get the error
I had the same issue. I removed the repo from the GitHub Windows client (right-click menu) and re-added it. When I re-added, I noticed I had about 300 uncommitted changes and it was reporting a memory error. I discarded all the changes and then sync started working fine again. (Rookie Git user - I'm sure there are better ways to do this on the command line)
