QGIS ARM 3.36 Python Console crashing issue

[tsmcgrath]

QGIS Version: 3.36.3 - Maidenhead
Qt version: 5.15.8
Python version: 3.11.9

I have a script that I run in the Python console. Previously this script was working. Now it crashes QGIS.

Repro:

• Download needed python code and QGIS data & project (link times out. If timed out I can get you a new one): https://www.dropbox.com/t/UjlXOCiaHSTKLGAM
• You'll need to edit the path's to point to the current file locations.
• Open QGIS 3.36 arm release. I am using a Mac M1.
• Open CanopyCoverMap.qgz QGIS Project
• Open Python Console
• Open Editor
• Paste mapgen_canopy.py into python editor
• Execute.

Result:
QGIS crashes. See attached crash report.

I can run an extremely similar script on another dataset (geology) and it works just fine. So, I thought the crasher must be caused by bad data. I regenerated the core dataset by intersecting two polygon datasets. It still crashes. Could still be data but I do not get any crash report from QGIS. I'll go back farther in the input data to regenerate them, and I'll validate the geometry. Although the script is just making a map and not manipulating geometry.

This is the last log entry:

It turns out the QGIS dataset had invalid geometry. So, the only action is to decide if it is a bug for QGIS to crash silently.
