[Windows] /feedback upload repeatedly fails and causes severe system slowdown

Title: [Windows] /feedback upload repeatedly fails and causes severe system slowdown

I encountered a scheduled Automation failure in the ChatGPT/Codex desktop app and attempted to report it using /feedback.

The feedback upload repeatedly failed.

Environment:

• OS: Windows
• App: ChatGPT/Codex desktop app
• App version: Unknown
• Date: 2026-08-12 KST

Observed behavior:

1. I opened /feedback from the existing Codex conversation containing the diagnostic report.
2. The first three upload attempts failed.
3. During those attempts, the entire computer became severely unresponsive and the mouse cursor barely moved.
4. The desktop app also terminated unexpectedly during an earlier attempt.
5. I restarted both the app and the computer, but the problem continued.
6. I then disabled “Include all browser tabs and browser logs” and tried again.
7. The upload still failed with “Feedback upload failed.”
8. The displayed feedback/session ID remained unchanged.

Expected behavior:

• The feedback should upload successfully.
• Collecting or uploading diagnostic information should not make the computer unresponsive or crash the app.

Underlying issue I was attempting to report:

• An ACTIVE weekday Automation scheduled for 2026-08-12 08:40 KST did not create a heartbeat Submission.
• The same Automation ran successfully the previous day.
• A separate Automation test succeeded later that day at 12:49:57 KST.
• A detailed diagnostic report is available.
• The relevant session/thread identifier is being kept privately and can be provided to an OpenAI team member if requested through an appropriate channel.

Attachments:

• Screenshot of the feedback upload failure
• Screenshot of the unexpected app termination

Sensitive identifiers have been removed from the public screenshots.

Start by reproducing the /feedback upload failure on Windows, testing both with and without browser tabs and browser logs included. Observe whether repeated attempts cause system unresponsiveness or app termination; done means diagnostic feedback uploads successfully without severe slowdown or a crash.
