vtkRenderWindow from VTK 9.1.0 does not open from python 3.10.2 on M1 macbook on macOS 12.1

This behavior is expected?

I’m not sure what you mean by that, I included the imports you mention. Although it should be noted that

import vtkmodules.vtkInteractionStyle
import vtkmodules.vtkRenderingOpenGL2

Are already part of the example code I linked in the OP. replacing with

from vtkmodules.vtkInteractionStyle import vtkInteractorStyleSwitch
import vtkmodules.vtkRenderingOpenGL2

makes no difference

I’m glad this topic is getting some discussion now that someone else has replicated the issue. I imagine it has something to do with macOS
