Description
When launching any QtWidgets application on macOS with QT_DEBUG_PLUGINS=1, it segfaults or aborts on exit. This works properly with Qt 6.2.4.
This:
QT_DEBUG_PLUGINS=1 python3 -c "from PySide6.QtWidgets import QApplication; QApplication([])"
fails with:

Similarly, launching e.g. QT_DEBUG_PLUGINS=1 6.3.1/macos/bin/pixeltool.app/Contents/MacOS/pixeltool in my Qt directory fails with:
pixeltool(7575,0x10f7635c0) malloc: *** error for object 0x7fbbc150e0e0: pointer being freed was not allocated
pixeltool(7575,0x10f7635c0) malloc: *** set a breakpoint in malloc_error_break to debug
