[Windows] Remote Control cannot be enabled and feedback upload also fails

What version of the Codex App are you using (From “About Codex” dialog)?

26.818.5229.0

What subscription do you have?

ChatGPT Plus

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

Remote Control cannot be enabled in the ChatGPT/Codex desktop app on Windows.

Steps to reproduce

1. Open the ChatGPT desktop app.
2. Go to Settings > Connections.
3. Select “Control this PC”.
4. Click “Allow”.

Actual result

Remote Control fails before displaying the mobile pairing QR code.

The error messages observed across multiple attempts include:

• “无法启用远程控制。请确保仅有一个 ChatGPT 实例在运行”

(“Unable to enable Remote Control. Make sure only one ChatGPT instance is running.”)

• “无法检查安全要求。请重试”

(“Unable to check security requirements. Please try again.”)

• “无法启用远程控制。请重试”

(“Unable to enable Remote Control. Please try again.”)

Only one top-level ChatGPT app instance/window was running when the error occurred. The additional processes visible in Task Manager appear to be normal helper processes.

I have already tried:

• Completely closing and restarting the app
• Restarting Windows
• Resetting the ChatGPT app through Windows Settings
• Reinstalling the latest x64 MSIX package
• Confirming that no Windows system proxy is configured

The problem still occurs.

Submitting feedback from inside the app also failed with the message:

“反馈上传未成功”
(“Feedback upload was unsuccessful.”)

Feedback ID:

01a02d3d-ce43-77f0-ba58-67d414ef6bf6

Expected result

Remote Control should be enabled successfully and the app should display the QR code used to connect a mobile device.
