installing Experience Builder SDK npm start error 4091

So, I installed Experience Builder SDK successfully on our production portal, but then tried to move it to our test portal.

I've been able to change the "https://localhost:3001/" to use the Client ID from the Experience Builder credentials on the test portal. (Note: I have already deleted the Experience Builder Credentials from the production portal.)

However, when I try npm start from the windows command prompt, I get the EADDRINUSE error, errno -4091 on port 3000.

I tried:

netstat -ano -p tcp |find "3000"
taskkill /F /PID <PID>

where <PID> is the far-right number from the netstat command, as described in this post: https://community.esri.com/t5/arcgis-experience-builder-questions/arcgis-experience-builder-uninstal...

 

However, I still get the same error.  Any advice on how to uninstall and reinstall Experience Builder SDK?
