The shortcut to Jupyter Notebook is messed up. If you go to the properties of the shortcut and go to the field Target you will see this:
"C:\Program Files\ArcGIS\Pro\bin\Python\cwp.exe" "C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3" "C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\python.exe" "C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Scripts\jupyter-note
They want to put in there more than is possible, hence the cut-off notebook.
If you would copy this manually in a command prompt or batch file with the completed paths it wont start.
But, if you put this in the Target field: "C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Scripts\jupyter-notebook.exe" it works it loads the config file for jupyter
