REG->6.8.0: crashes after "import PySide6; from PySide6.QtCore import *"

Since the upgrade from PySide6 6.7.3 to 6.8.0 a Python application now crashes with a segmentation fault.

I was able to reduce the code for reproducing the problem to a single line:

import PySide6; from PySide6.QtCore import *

When running this code in Linux, for example with Python 3.12.7, a segmentation fault occurs:

$ python3 -c "import PySide6; from PySide6.QtCore import *"
Segmentation fault (core dumped)

This problem might also occur on other operating systems and with other Python versions.
