hard crash when using auto-hide docks in 4.2.1

[RubendeBruin]

The script below works fine in 4.1.0.3 but results in a "Process finished with exit code -1073741819 (0xC0000005)" after upgrading to 4.2.1 (PySide6-Essentials-6.6.2 PySide6-qtads-4.2.1 shiboken6-6.6.2)

Env:
Python 3.11
Windows 11

Not sure if this is PySide6QtAds related or QtAds. Tried to reproduce in PyQtAds but that package on pip is still at version 3.8.1 so no luck there.

"""Demo / Test file for auto hide docks in PySide6QtAds.

A custom close event is added to the docks to make them return to the hidden state when the close button is pressed.
