mesh.write_vtk and pyvista.read functions are no longer compatible

[micmitch]

I recently installed a new conda environment on a bigger computer to speed up inversion results plotting.

When I tried to run my plotting script pyvista.read() is no longer able to read the .vtu file created by mesh.write_vtk()

I am not sure if this is an issue with how discretize writes the model file or how pyvista reads it. Interestingly, I can still load the .vtu into ParaView.

I tried to attach a notebook or .py file showing a simple example but that isn't allowed.... Happy to send this example some other way if that is helpful.

After creating the octree mesh and model I write the file using this command

mesh.write_vtk('rhoTrue_2BlkTest.vtu', models={"rho":rhoTrue})

Then I try to read it back in using pyvista
rhoInv_vtu = pyvista.read('./rhoTrue_2BlkTest.vtu')

This results in the following Error Message:
