What issue are you seeing?

When I give a prompt to Codex using the GPT-5.6 model, it starts running normally, but after a while, it gets stuck while processing.

What steps can reproduce the bug?

Open Codex, select the GPT-5.6 model, and enter a prompt. The task starts running normally, but after some time, it gets stuck and stops making progress without completing the request.

What is the expected behavior?
