Desktop browser: Runway file upload blocked by Auto-review; unclear supported recovery path

Summary

Browser automation for https://app.runwayml.com in the Codex desktop app on macOS stopped at a file-upload step after an Auto-review denial. Earlier browser operations in the same task had worked.

Observed behavior

• A local PNG upload through the browser file chooser was rejected at setFiles with Browser Use rejected / Auto-review denied.
• The agent was instructed not to retry through alternate browser surfaces or indirect execution and stopped.
• The user did not see a separate approval prompt.
• Signing in again and reverting a site permission from Always allow to Requires approval did not establish recovery.
• A separate read-only plugin authentication check had succeeded; that is not evidence that browser automation was restored.
• The exact initial cause remains unknown. This report describes earlier observations, not a fresh reproduction.

Environment

• Codex desktop app on macOS, built-in browser
• Approval reviewer: auto_review
• Observed on 2026-09-11, Europe/Moscow
• Exact app and OS versions: not yet verified

Requested clarification

1. Is uploading a local image through the desktop built-in browser supported?
2. Is this an expected restriction or a possible integration/approval-state error?
3. What official, narrowly scoped recovery path is available in the desktop app if the denial was incorrect?
4. Which additional sanitized diagnostics would help?
