QGIS crashes on getting items of mapCanvas scene if features are identified

[zmilucero]

Describe the bug

Similar to issues #32894 and #32700, QGIS now seems to crash if features have been identified using Identify Features and the identify result has not been cleared (either via right-clicking or the Clear Results button in the Identify Results panel) prior to getting items of mapCanvas scene.

How to Reproduce

1. Load in vector dataset (tested with polygons and points)
2. Identify any features
3. Clear identify results
4. Run iface.mapCanvas().scene().items() in the console; it works as expected
5. Identify any features again
6. Without clearing, run iface.mapCanvas().scene().items() in the console; it will hang for a few seconds and then produce a "QGIS unexpectedly ended" dialog or, in some cases, silently crash
