Hi @SGaist, I took you advice and finally found out where the problem is.
I looked into Wependency Walker and realized that I can import PySide6.QWidgets before I import wiggly, So that the dlls needed is already loaded for wiggly.
I've been testing wiggly using one single import wiggly in IPython, not runing the main.py directly in the examples, trying to copy dlls from one place to another, and kept getting ImportErrors.
Now I write:

import PySide6.QtWidget import wiggly

and it works.

Thanks for your help!
