Happens sometimes when you update through anaconda navigator and have to start as Admin.
Two things to do:
Copy(Replace) "migrate" file from the .jupyter folder under admin to the user folder.
Create new shortcut for "jupyter-notebook.exe" in the "Scripts" folder of the anaconda installation folder. Paste this shortcut also into the same folder where all other shortcuts for the anaconda packages are placed.
Extra: you can change the location where the Jupyter Console should open with a right-click on the shortcut and change properties.
