Summary

Codex frequently gets stuck at “Thinking” until I manually interrupt the task. This happens not only during /goal mode, but also during normal prompt-based tasks.

Environment

• Codex surface: Windows desktop app
• OS: Windows 11
• Codex CLI version: not applicable; CLI is not used
• App version: 26.616.71553
• Execution mode: worktree

Repro steps

1. Open Codex on Windows.
2. Start a task in either /goal mode or normal prompt mode.
3. Codex begins executing.
4. After a while, it gets stuck at “Thinking”.
5. There is no visible tool/action progress.
6. Manually interrupt the task.
7. Continue/resume the task.
8. Codex starts working again.

Expected behavior

Codex should continue execution, or clearly show what it is waiting for.

Actual behavior

Codex remains stuck at “Thinking” until I manually interrupt it. After interrupting and continuing/resuming, it starts working again.

Frequency

This happens frequently, especially during longer tasks.
