The first message in a new Codex chat works normally, but when I send a second message in the same conversation, Codex fails with:

{"value":{},"source":"owned","hooks":[],"promises":[]}

The error is reproducible and happens after the first successful interaction.

What steps can reproduce the bug?

Open Codex Desktop on macOS.

Create a new Codex chat.

Send the first message.

Codex responds normally.

Send a second message in the same chat.

The second message fails and the following error appears:
