Try unzipping the folder closer to the root of the directory. This error usually occurs because the file is placed too deep inside of a directory, which eventually leads to a file path that contains too many characters.
I’m experiencing a similar problem, not getting the same error of path name being too long (though it appears similarly long), rather “UnauthorizedAccessException”, see attached. I searched the path and on get to .git folder, don’t see the file itself showing, even with Show Hidden enabled. The UnrealEngine-Release resides within Documents, so don’t see how the path could be too long anyway. Thanks for advice.
