What issue are you seeing?

When submitting a specific task to Codex, the request appears to get stuck. The CLI hangs indefinitely without returning a response or throwing an error message. I am unable to determine if this is caused by a network connection timeout or a bug within Codex itself.

What steps can reproduce the bug?

Uploaded thread: 019ae867-824a-77e0-bda9-0a4451c0e762

What is the expected behavior?

The CLI should either complete the request and return a response, or fail with a clear timeout/error message within a reasonable timeframe.
