Unable to Sign In in AppStudio

[JamesGough]

Starting today, I am unable to Sign In in AppStudio with my ArcGIS Online account. I tried uninstalling and re-installing AppStudio but that made no difference. Before today I had no issue signing in.

The sign-in prompt comes up, I enter my credentials and click "Sign In", and the prompt disappears but then nothing happens; the busy indicator in AppStudio just keeps spinning. I even intercepted the web traffic and it is able to successfully make the request to ArcGIS Online and the authentication tokens are returned.

App Studio 5.4.142 on Windows 10 (OS Build 19044.1889)

Hi @YukiOZAWA2,

If you are encountering the sign in issue on Mac, you only need to replace the .dylib file. If the problem persists after following the steps in the support patch page, please contact support for further assistance. 

Best,

Trevor

Was having the same issue with AppUpload and AppMake. Replacing libAppBuilderPlugin.dylib in both worked for me, thanks @YukiOZAWA2
