What's Wrong?

I just uninstalled and reinstalled Claude app for Windows 11 after I asked Claude how to fix. It didn't fix the issue:
When I launch the Claude Desktop App I log in with my email address. Claude then asks for a security code that was sent to my email address. I check the email and it says: "Let's get you signed in
--
Sign in with the secure link below

Then displays a black button with the label Sign in to Claude.ai
Clicking the button launches Edge browser and logs me in so the app is still waiting for the security number.

What Should Happen?

Claude email should give me a security code which I then enter into the Windows 11 Claude Desktop app and it logs me in through the app
