[Bug] Can't restart the jupyter-dash app through rerunning the jupyter cell

[mltja]

In jupyter-lab I can't restart the jupyter-dash app through rerunning the jupyter cell.

Error message:

Address already in use
Port 8050 is in use by another program. Either identify and stop that program, or start the server with a different port.

Problem occurs with: dash==2.6.2 and werkzeug==2.2.2 problem is solved with downgrading werkzeug to 2.2.1
