Hi I am trying to read in a .vtk file to Paraview in Windows 10 system. However, when i click the Apply button, it crashes the Paraview.

I have attached the vtk file below. Any advice would be appreciated.

Your cell array size is wrong, you only have 20 values so you should have `CELLS 4 20` instead of the 40 that you had. (4 cells and 20 index/values in total)
