Problem with jupyter-notebook

[Artemio González López]

I am having a problem with the jupyter-notebook port (both 3.11 and 3.12) under MacOS 14.5 (Sonoma) on an M1 13” MacBook Pro. More specifically, jupyter-notebook launches and allows me to navigate my hard disk. However, when I click on a notebook to try to edit/run it a new tab is opened in Safari, but it remains empty, and I get the following error in the terminal window:

    The above exception was the direct cause of the following exception:

Any idea what the problem might be?

Thanks a lot in advance,
