crash in "modern Windows" style plugin when using a QStyledItemDelegate (Windows 11)

null pointer when running the code in the sample project below, which uses a custom subclass of QStyledItemDelegate, using qmodernwindowsstyle plugin in Windows 11 (works in Windows 10, at least on my system or when not using the style plugin).

Stacktrace:
