I have temporarily the AuthN mode to classic, but that will soon be deprecated, so it is obviously not a solution.

Can you follow these steps so that we can get more information on what's going on?

Enable trace logging

• Open the Command Palette (cmd/ctrl+shift+p)
• Run the Developer: Set Log Level... command
• To the right of Trace, click the double check mark button. ✔️ ✔️ (enables trace logging as the default)

Now wait for the issue to happen or trigger it...

Getting the logs

• Open the Command Palette again (cmd/ctrl+shift+p)
• Run the Output: Show Output Channels... command
• Choose Microsoft Authentication
• Copy and paste the contents of what opens in the panel in this issue (if the contents is too large, you may need to upload it as a file)

Reverting trace logging (optional)

When we're done here, to revert the log level back to the default:

• Open the Command Palette
• Run the Developer: Set Log Level... command
• To the right of Info, click the double check mark button. ✔️ ✔️ (to set the default back to info)

It looks like this issue is related to the Microsoft Identity authentication broker on your OS. This is not a component maintained by VS Code - It simply leverages it for authentication.

Please refer to the Feedback and support section of this post for assistance with these types of issues. This article also talks about what authentication brokers are and why they're important.

Closing this as out of scope of VS Code...
