macOS/Qt6: constructing QgsCoordinateReferenceSystem crashes

[kommen]

What is the bug or the crash?

constructing an QgsCoordinateReferenceSystem(4326) crashes QGIS

I'm using the macOS/Qt6 build from @m-kuhn provided here: #60039 (comment)

previous versions of QGIS don't crash. (I tested QGIS 3.40.2, the offical build from qgis.org)

QgsCoordinateReferenceSystem(4326) is used in the https://plugins.qgis.org/plugins/StreetView/ plugin, which I try to make work with Qt6.

Steps to reproduce the issue

1 ) Go to the Python Console
2) evaluate QgsCoordinateReferenceSystem(4326)

Addendum:

Constructing it with QgsCoordinateReferenceSystem("EPSG:4326") instead of QgsCoordinateReferenceSystem(4326) works as expected and doesn't crash.

Just an observation: QgsCoordinateReferenceSystem(4326) constructor is deprecated.
The issue doesn't occur on Windows running QGIS 3.41.0-Master a2c3471 (Qt 6.6.3, Python 3.12.8 - OSGeo4W).
