Verbose output shows the following

ℹ Aborting request to "https://signin.amazonaws-us-gov.com/saml"
ℹ Request to "https://signin.amazonaws-us-gov.com/saml" has has been successfully blocked
ℹ Error while authenticating in headful mode page.waitForResponse: Target page, context or browser has been closed

Honestly have no idea what is occurring here.
I have disabled AV, Firewall, and any other software that might block it
