This problem happens when I loaded a data exceed 2GB that was generated by AMReX, with Paraview 5.13.0 under Windows 10. See details at The WriteMultiLevelPlotfile or Paraview seems to overflow for large data sheet · Issue #4167 · AMReX-Codes/amrex · GitHub. However, when loading the data unber Ubuntu 22.04 with the Linux binary of Paraview 5.13.1, every thing goes correctly. Therefore, there might be a issue for the data type that used in Paraview under Windows (4 bytes or 8 bytes). I am not sure whether it is long or not.
