**Possibly related, but my failure appears to happen earlier, during reasoning/context recovery rather than inside Python/container execution.**

**Environment**

- ChatGPT Plus
- Web, Microsoft Edge on Windows
- 29 September 2026
- GPT-5.6 Sol

**Symptoms**

- Existing long-running development chat showed `Analysis paused`.
- Later turns displayed `Analyzed` repeatedly on separate lines, with no substantive response.
- Some attempts then showed only the pulsing activity circle and never progressed.
- I reproduced the same behaviour in a **brand-new chat** , so this does not appear to be caused solely by a long conversation.
- Both **Instant** and **Medium** thinking modes were affected.
- The fresh chat contained only a handover/seed prompt, one previous-build ZIP, and two small screenshots.

**Important detail**

I manually stopped one stalled turn. ChatGPT then reported from its execution trail:

> “I did not get as far as modifying Build 100, running tests, or packaging a new build. I stalled in reasoning/context-recovery.”

So in this case the turn appears to be **stalling before file modification or tool execution begins** , rather than failing while Python/container code is already running.

**Observed pattern**

The system intermittently recovers and can complete small graphical/code changes successfully, then later falls back into the same stalled state.

This looks related to the execution/orchestration problems reported here, but possibly at an earlier stage in the pipeline. A fresh chat did not reliably clear it.

Happy to provide screenshots/timestamps if useful.
