Error when trying to load module RVesselX

Hello, I’m trying to install an extension SilcerRVXLiverSegmentation, and when I couldn’t load the module.

Here is the error log:
Traceback (most recent call last):

from .VesselHelpWidget import VesselHelpWidget, VesselHelpType
ModuleNotFoundError: No module named ‘RVXLiverSegmentationLib.VesselHelpWidget’

Does anyone know how to solve this problem? I have no knowledge in Python and am utterly confused.

The problem was that the developers added a new file ( but forgot to add to the Slicer extension package. I’ve submitted a pull request that fixes the issue:

In the meantime, you can download the missing file and copy it to C:/Users/karis/AppData/Local/NA-MIC/Slicer 5.1.0-2022-05-18/NA-MIC/Extensions-30955/RVesselX/lib/Slicer-5.1/qt-scripted-modules/RVXLiverSegmentationLib
