What issue are you seeing?

In Codex Desktop on Windows, the integrated terminal panel flashes briefly and immediately closes when I try to open it.

PowerShell works normally outside Codex. I can open PowerShell directly from Windows without any issue.

Inside Codex, the terminal does not stay open and does not attach to the current thread. Codex reports that no app terminal session is attached to this thread.

What steps can reproduce the bug?

1. Open Codex Desktop on Windows.
2. Open a local workspace/thread.
3. Close the preview browser panel if it is open.
4. Try to open the integrated terminal panel.
5. The terminal panel flashes briefly and immediately closes.

Expected behavior:
The integrated terminal panel should stay open and attach to the current Codex thread.

Actual behavior:
The terminal panel closes immediately. PowerShell works normally outside Codex.

What is the expected behavior?
