[Windows desktop app] Second message remains stuck loading and is never sent

Summary

In the ChatGPT desktop app for Windows, the first message in a conversation is sent successfully, but the second message remains stuck loading and never reaches the conversation. The send button becomes disabled or appears gray.

The problem occurs in both new and existing conversations and affects ChatGPT and Codex. ChatGPT in the web browser works correctly with the same account.

Steps to reproduce

1. Open the ChatGPT desktop app on Windows.
2. Start a new conversation.
3. Send “One” and wait for the response.
4. Send “Two”.

Actual result

The second message remains loading indefinitely and is never added to the conversation.

Expected result

The second message should be sent normally and the conversation should continue.

Troubleshooting already attempted

• Restarted the application and Windows.
• Updated the application.
• Used the Windows “Repair” option.
• Used the Windows “Reset” option.
• Uninstalled and reinstalled the application.
• Tested new and existing conversations.
• Tested ChatGPT and Codex.
• Closed ChatGPT Classic completely.
• Tested with a different network using a mobile hotspot.
• Confirmed that ChatGPT works correctly in a web browser with the same account.
• Confirmed that no system proxy or active VPN is configured.

No source file or test is identified. First reproduce the issue in the Windows desktop app by sending a second message in both new and existing conversations, then compare ChatGPT and Codex behavior with the web browser. Done means the second message is sent and appears in the conversation normally.
