Please update the CGNS library; large CGNS files do not open on Windows
A critical problem with opening large files on Windows was patched more than 1 year ago in https://github.com/CGNS/CGNS and released in v3.3.1 last July. I tried fixing it in the ParaView git repo, but that was not allowed (of course).
If you update the version of CGNS used in ParaView, the windows users of ParaView can enjoy their large CGNS files too
