Why not working monai pathology?

I installed monai to 3d slicer 5.0.
It was working very well(as using radiology with sample files).
so I want to change from radiology to pathology and other sample files.
but in this pic, it was not working…
how to work normally?

MONAI Label for pathology introduced a dependency on OpenSlide, so you need to install that on your system or else disable the pathology app from MONAI Label if you don’t need it - I don’t think there’s a high level option so you would need to edit the code.
