ran into the same problem, the C:\Users\Eneth Gomez\AppData\Roaming\jupyter\runtime folder doesn’t have admin rights causing Jupyter notebook starting issues.
right click on the folder and add admin read/write rights or double click on the jpserver-20488-open.html file, if admin rights are not OK you’ll get a pop-up to enable them.
