QtDesigner in Windows PySide6 (installed from Pypi with pip) can't show the code for Python through the "Form > View Python code..." menu entry. It fails because it expects the executable file "uic.exe" and library file "QtCore.dll" to be in the folder "venv\Lib\site-packages\PySide6\bin". This folder does not exist.

Problem can be easily circumvented creating the folder and copying those two files to this folder.
