Loading a 2x2x2 dimensions lagrange hexahedron element type of order 1 and trying to visualize the slices, clipping or contour leads to segmentation fault. I suspected corrupted vtk file so I created a sample element from , sources\>alphabetical\>unstructured grid types; Properties: dimensions- 2x2x2, lagrange hexahedron,cell order-1.  
I chose the default location of clipping or slicing and the Paraview closes with segmentation fault.  
Anyone able to reproduce this and check? This seems to be a major bug…

I can reproduce. I’ve reported an issue here: [https://gitlab.kitware.com/paraview/paraview/issues/18761](https://gitlab.kitware.com/paraview/paraview/issues/18761)
