Not able to az login #32527
Description
Describe the bug
I'm using az login to develop features and functionalities in my software. When I was using version 2.61, it worked fine. Recently, I updated to the latest version, and now I can no longer log in.
Related command
az login
Errors
No specific error message appears; the screen just stays in an infinite loading state and never completes the login.
