Did you look, in the README.md in the paragraph Register the client app (active-directory-dotnet-deviceprofile, did you go through step 5 (editing the manifest to set allowPublicClients to true)

In case anyone else finds this through a search engine, I also ran into this error when acquiring a token with the system browser on .NET Core 3.0. I had set http://localhost as a redirect URL in my app, but accidentally set it to type "Web" rather than "Public client/native (mobile & desktop)".

This did the trick for us! Thanks!
