Qt Creator randomly won't update .py file with changes from .ui file

[BGrimaud]

I'm using Qt Creator 11.0.2 with Qt 6.4.3 to develop an app using PySide 6 and Python 3.12.

Whenever I make UI changes to mainwindow.ui with Qt Creator, I click the "Build" button with the hammer icon, after which the ui_mainwindow.py file is updated. I can then interact with new or updated widgets from main.py.

However, the .py file sometimes refuses to change. I can click the "Build" button as much as I want, clean up, start again, restart the app, the file simply won't update. After a while, or through some other factor I cannot identify, the file will finally update and I can carry on.

Any idea of what could be the issue ?

@BGrimaud
If you delete the ui_...py file and resave does that recreate it, and reflect new changes?
Do you have the option to try a newer version of Creator?
