box_maker_generic_generator and Festi's Boxes.py extensions do not work

[Deltaplc]

Hi sorry to bother you... I have installed ten extensions of this wonderful package on Inkscape 1.2 (portable app) with Win10. All work except 2: "box.py" and "box_maker_generic_generator". As for "box_maker_generic_generator" it's not a big problem for me because I used an older version of it that I used on inkscape 1.1 and once I ported it to 1.2 it worked fine! As for "box.py" I would have liked to use this new version because it has some new applications but it really doesn't want to work!! I tried and tried but it doesn't work! I attach some errors that are generated:

stderr: Fatal Python error: init_sys_streams: can't initialize sys standard streams Python runtime state: core initialized Traceback (most recent call last): File "C:\Users\Davide\Documents\Inkscape_portatile\InkscapePortable_1.2.2.paf\InkscapePortable\App\Inkscape\lib\python3.10\io.py", line 54, in ImportError: cannot import name 'text_encoding' from 'io' (unknown location).

I also tried installing box.py on another PC... with inkscape 1.2 installed in c: and python 10 & win10.. But unfortunately it doesn't work in this case either. I also tried with "python-interpreter" etc.... But it doesn't work!

Maybe I'm doing something wrong?? Can you give me some advice to solve the problem?

Thank you! Greetings Davide
