I just installed Python 3.14 on Windows 11. Then I created a new virtual environment and pip-installed Leo into it. PyQt6.sip got installed and Leo ran normally. Something went wrong when @rengel tried installing Leo, I think, because PyQt6 didn't install normally.
I'd suggest creating a venv like I did and trying it that way.
