It will work for polydata but not for pointset. There is a flag in the code snippet to test the two cases.
To see if it is not due to installation issues I created a Colab notebook also.

Also, there is one line by mistake in the documentation which needs to be removed.
https://vtk.org/doc/nightly/html/classvtkPoissonDiskSampler.html
“generate point normals using local tangent planes”
I am also uploading a small test triangle mesh to see if vtkPoissonDiskSampler works on it.
It crashes for me.
