Cannot clone repository on Windows
I couldn't find an existing issue about this.

You cannot fully clone this repository on a Windows system because the Conflux SVG (svg/con.svg) uses a reserved filename (CON)
See the full list of reserved names on this page: https://docs.microsoft.com/en-au/windows/win32/fileio/naming-a-file

As far as I'm aware, the only possible fix is to change the filename. Windows ignores the file extension, so a prefix or postfix would work.
