Jupyter notebook 7.0.2 error messages on Mac OS 13.5, Apple Silicon

I have been using notebook 6.5.4 on Mac OS 13.5 on Apple Silicon for a while.

Installation is maintained by Homebrew installed Python 3.11.4. All python packages are maintained using pip. Default browser is Safari 16.6

I get the following messages
