Upgrade CGNS to 4.1.1
A new release is available: https://github.com/CGNS/CGNS/releases/tag/v4.1.1
There is a low level API change in CGNS.Thus adaptation are done there: https://gitlab.kitware.com/MicK7/paraview/-/tree/cgns_cgio_api_changes The changes do not modify the reader behavior (like it still handles memory allocation for type transfer for hdf5) since ADF is still in use by some people. When CGNS 5.0 is released next year without ADF support requirement, maybe it will be possible to use fully the new low level API (and have a code more maintainable)
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
