It looks like it's a caching issue. Edge is still trying to load the extension from the local debugging host started when you run gulp serve.

Try accessing the SharePoint site using a private (incognito) browser session in Edge to confirm. If it loads correctly in that session, then try doing a full reload using CTRL-F5 in the regular (non-incognito) browser session. You can also trying clearing cookies and local storage.

I hope this helps.
