What issue are you seeing?

Codex App on macOS has been unusable for about 8 days on my ChatGPT Plus account.

I already submitted in-app feedback with logs.

Correlation ID: 019e3ba7-bb8d-7270-b4e3-664a680a895d

Error: invalid_request_error / invalid_function_parameters

Invalid schema for function '_search_content': schema must have type 'object' and not have 'oneOf'/'anyOf'/'allOf'/'enum'/'not' at the top level.

Already tested:

• ChatGPT Plus is active
• fresh new Codex project
• app fully uninstalled and reinstalled
• Spreadsheets and Presentations plugins disabled
• different Codex models tested
• simple prompts tested
• issue persists for days

Expected behavior: Codex should respond normally or create/read files in a fresh project.

Actual behavior: Every prompt immediately fails with the invalid schema error above.

This does not look like a plan, usage limit, model, plugin, or repository issue. It appears to be a broken Codex tool/schema registration or account rollout state.

What steps can reproduce the bug?

1. Open Codex App on macOS.
2. Create a fresh new project.
3. Send a simple prompt, for example: "Create a test.txt file with the content: Hallo Codex".
4. The request immediately fails.
5. The same happens in existing projects and fresh projects.
