Spectral Library Tool Plugin Error
I am working with the Spectral Library Tool Plugin. The plugin is installed, but when I try to generate a spectral library from a hyperspectral image loaded in the QGIS canvas, I am getting the following error. 

AttributeError: 'QSortFilterProxyModel' object has no attribute 'rootGroup'

I was able to work with this tool on one of my PCs but on the other one, I am getting this error. 

Sincere request for any solutions.

This is a known issue in QGIS versions 3.19 and upwards.
The problem seems to be with broken python packages.

Please let us know what OS you are using.
