Empty Environment Path - Package Path Location Blank When Updating to v.69

I seem to be able to update to the latest version of Core Meta SDK (v.69) just fine, but then after the Unity Editor restarts, the path to package cache is wiped and the Unity console endless prints the error below.  Has anyone else experienced this and if so what was the solution? 

I am going to try adding an environment variable to see if that has any effect, but any help or feedback is appreciated. 

There was a path set here prior to updating but it is blank with no option to add a path after updating and restarting the editor.
