py-notebook: Jupyter notebook fails to open notebooks (MacOS 14.5 (23F79), M1 MacBook Pro)

[agl2015]

Jupyter-notebook (both versions 3.11 and 3.12) under MacOS 14.5 (Sonoma) on an M1 13” MacBook Pro does not properly handle opening of notebooks. More specifically, jupyter-notebook launches normally and allows one to navigate the hard disk hierarchy in a Safari tab. However, after double clicking on a notebook to edit/run it a new tab is opened in Safari, but it remains empty, and the following error message appears in the terminal window:
