2019-04-20 19:00:26 +0100 commented question Sage Notebook crashes immediately

Thanks for the guidance on how best to handle the large screen dump in my question - will keep that in mind going forward.

The "port=9999" trick seems to have worked - the Jupyter Notebook server starts, and I'm able to launch a new SageMath 8.6 session. Now I can proceed with studying the documentation and learning how to use it.

Thanks very much for your help!

New installation of Windows binaries, version 8.6 (Windows installer 0.4.2), on 64-bit Windows 8.1 system with 8GB of RAM. Clicking on the "SageMath 8.6 Notebook" desktop icon opens a terminal window and displays the message "Please wait while the Sage Jupyter Notebook server starts", but the window closes within 2 or 3 seconds.

Would appreciate any guidance on troubleshooting - happy to study any relevant documentation if someone can point me in the right direction.

When running sage --notebook=jupyter in the shell I get:
