What issue are you seeing?

Description: After today's update of the Codex app, I consistently receive an "Oops, an error has occurred" message at the end of specific tasks.

Actual Behavior: The assistant successfully completes the task (the file editing/writing itself works perfectly fine), but immediately after it finishes, a generic red "Oops, an error has occurred" message appears at the bottom right of the screen with "Check for updates" and "Try again" buttons.

What steps can reproduce the bug?

Steps to Reproduce:

1. Open the Codex app.
2. Ask the assistant to perform a task that involves modifying/editing files (e.g., editing scripts, .md files, or any other code writing).
3. Wait for the generation to complete.

What is the expected behavior?

Expected Behavior: The task finishes smoothly, and the chat is ready for the next prompt without any errors.

Additional information

Additional Context:

• This issue does not happen during "read-only" tasks (like reading audits, analyzing code without modifying it). It only triggers after modifications/edits.
• The actual work (script modification) is done perfectly despite the error message showing up at the very end.
• I have attached a screenshot showing the error state.
