VS Code Codex extension freezes immediately / after paste, no re-auth prompt despite invalidated token

What version of the IDE extension are you using?

26.602.40724

What subscription do you have?

pro

Which IDE are you using?

vs code

What platform is your computer?

Linux 6.12.90+deb13.1-amd64 x86_64 unknown

What issue are you seeing?

The official OpenAI Codex / ChatGPT VS Code extension freezes the VS Code window on Debian 13 KDE 6 and debian 12 kde 5.

The issue happens rapidly when opening the Codex side panel. After a short time, VS Code becomes unresponsive.

Now, the extension also does not ask me to sign in again, even though the Developer Tools console shows a 401 token_invalidated response from the OpenAI backend.

What steps can reproduce the bug?

Start VS Code on Debian 13 KDE 6 or debian 12 kde 5 (all two uptodate).
Open the Codex / ChatGPT side panel.

Try to use the prompt composer.
codex sidepanel seem don't auth
VS Code becomes unresponsive / freezes.

Now : no prompt area, no history

What is the expected behavior?

The Codex side panel should remain responsive, showing chats history and prompt section.
If the authentication token is invalidated, the extension should clearly ask the user to sign in again.
