consent blocks login

I'm encountering issues stepping through the auth flow where the extension successfully obtains a token but then fails to complete login with an output message "User did not consent to login". I've tried logging out, clearing browser cookies and rebooting but always the auth flow fails with this message in the logs.
In the flow itself I never see a consent dialogue- I have been using the extension successfully for a few weeks and likely consented when I first installed it. Instead, after selecting my account in the account picker the browser window displays "Just a moment", and refreshes this notification three times before closing. Maybe this is an upstream MSAL issue?

Start by reproducing the failure through the ado-codespaces-auth.authenticate flow and inspect the logs around the VS Code token and the "User did not consent to login" error. Check the account-picker and MSAL-related browser flow, including the repeated "Just a moment" page; done means the extension completes login after account selection or the upstream cause is clearly identified.
