New Computer - New Outlook not allowing me to sign in from my personal tenant.

I have been using the new Outlook client for months with no issues.  I have a new desktop, and when I tried to sign in to New Outlook from my O365 basic tenant account I received the following error:

On my old machine it has never been a problem.  I tried removing all the email accounts, and starting over, but something setting is being kept, and I'm not sure how best to fix.

I have two O365 email accounts, my work address, and my personal tenant address (O365 Basic).  The regular Outlook client works without any issues on the new computer, but missing the new Outlook.
