I cannot use ALPACA module

Dear Professors, friends and all members here,

I need your advice on using ALPACA.

I have installed the SlicerMorph extension. After installation, I am trying to use ALPACA module, but when I click on this module, nothing shown in the working tab(as in the attached photo) and this is what have been show in the Python interactor.
Python 3.9.10 (main, Aug 19 2023, 07:42:26) [MSC v.1935 64 bit (AMD64)] on win32

Please try with the newest stable (v5.6.1) that will be available later today, and then let us know if it doesn’t work.
