QT Creator crashes when opening a qmake project

[DavideXG]

I have a problem with Qt Creator (on Windows 10 22H2): whenever I open a qmake-based project, it forcibly closes without giving any error message.
I have tried rebooting several times and reinstalling Qt from scratch, even in various versions (6.5.3, 6.6.1, 6.7b1), and even manually installing Qt Creator 11.0 instead of 12.0.1, but nothing has changed. Also deleting Qt Creator settings folder in %appdata% or launching it with admin privileges didn't work.
This happens for any qmake-based project, even creating a new one.

Does anyone know what the problem might be?
Thanks

@DavideXG Did you try to disable anti virus software to see whether it makes a difference?

@jsulm Unfortunately, I can't disable it, but on another PC with the same av software, Qt Creator works. However, there are no events in the antivirus log.

I tried opening an empty .pro file and Qt Creator crashes even if the file is empty.
I also tried with Qt Creator 9.0.2 and 5.0.3 with the same result.

Update: I formatted the pc and installed Windows 11, Qt 6.7.0, Qt Creator 13 and it crashes again. Then I tried with another laptop, but same model (Dell Latitude 3520), and it crashes also on that pc! So it seems something related to some specific Dell driver for this product...
