I am following the PyQt6 tutorial using the Thonny IDE in Windows 11,and when I run the script I get the following error:

Traceback (most recent call last):
  File "C:\Users\tonyj\Scripts\Python\app.py", line 1, in <module>
    from PyQt6.QtWidgets import QApplication, QWidget
ModuleNotFoundError: No module named 'PyQt6'

If I call the script from Python it works perfectly. I've also tried it in PvCharm and VSCode: both display the same error. All systems (Windows, Python, Pip etc) are all at the latest version.

Thanks
