ShapePopulationViewer cannot open spharm output


I am trying spharm in Slicer Salt on Windows 11. I directly ran the extension in Slicer. I got two mice mandibles and I filled all the internal holes for the segmentations. I followed the tutorial from Salt website. The raw VOLs, input VTK, and label maps as well as the output from using the label maps are in this zip file. The source volumes are 129S1_SVIMJ and 129 X1_XVJ from OSF | High Resolution microCT scans of Inbred Mice.

I could not open the output in ShapePopulationViewer. The full log is here.The error message is:

ShapePopulationViewer standard error:
Qt: Untested Windows version 6.2 detected!
libpng warning: Interlace handling should be turned on when using png_read_image

I wonder if it is related to how I installed ShapePopulationViewer. I could not find it in the Extension Manager, so I downloaded v1.3.2_windows and added the .exe file to Slicer Modules. However, when I tried to load any file from the spharm output either in shapePopulationViewer in Slicer or the exe file, it just reported the above error and forced closing the app.
