Steps to reproduce:

• set QSG_RHI_BACKEND=gl
• Run C++ simple browser example
• Observe crash(es)

For Qt Designer, a crash occurs when dropping a QWebEngineView onto the form
since it forces GL ("Qt Designer: Enable the QWebEngineView, QQuickWidget plugins on Windows" qttools/89fef3e0671d6ff270e9b400f0d8696a46994453 https://codereview.qt-project.org/c/qt/qttools/+/392687 ).

Original report (Qt for Python)

In PySide6 version 6.7, utilizing QWebEngineView with OpenGL rendering (os.environ['QSG_RHI_BACKEND'] = 'opengl') leads to an immediate program termination, exiting with error code 1. This issue does not occur in version (<=6.6.3).

Additionally, Qt Designer in PySide6 6.7 crashes when attempting to load UI files that contain the QWebEngineView component or when interacting with the component option of QWebEngineView within the designer.

I tried to reproduce the problem on WSL Ubuntu and it didn't happen.

Reproduce:
Here is the Python code snippet to reproduce the issue:

import os
import sys
from PySide6.QtWidgets import QApplication
from PySide6.QtWebEngineWidgets import QWebEngineView

if __name__ == '__main__':
    os.environ['QSG_RHI_BACKEND'] = 'opengl'
    app = QApplication()
    view = QWebEngineView()
    view.setUrl("https://www.youtube.com/")
    view.show()
    sys.exit(app.exec())
