I followed the outlook learning path to create a task pane add-in. When I do npm start I get 'Failed to retrieve token silently.'. How do I find out whats wrong?

Question

Hi, I have been following this learning path https://learn.microsoft.com/en-us/office/dev/add-ins/quickstarts/outlook-quickstart-yo.

When I do the npm start it opens the browser at the login page and allows me to log-in. Then I get the following:

C:\Users\david\O2M>npm start

I see that almost exactly the same question was asked a year ago https://learn.microsoft.com/en-us/answers/questions/1533802/outlook-add-in-failed-to-sideload-due-to-authoriza but has no answer.

Can anyone tell me how to get past this? Is there a different approach that works?
