What issue are you seeing?

Additional critical detail:

The corrupted response does not terminate normally. Once the issue starts, Codex keeps generating gibberish continuously until manually stopped. This is not just a malformed answer — it appears to enter an infinite or non-terminating generation/streaming state.

Observed behavior:

• response starts normally or near-normally
• output degrades into multilingual/token-salad gibberish
• generation keeps going indefinitely
• manual stop is required

This makes the issue significantly more severe than a one-off corrupted text fragment.

The response continued generating indefinitely until I manually stopped it.
