Chat is unresponsive and doesn't interact with the messages I send

[alobaili]

Describe the bug
Sometimes when I open the Chat window and send a message, Copilot doesn't respond and the UI does not show any indication that something is happening. Even if I type the message multiple times.

Versions

• Copilot for Xcode: 0.46.0
• Xcode: 26.2 (17C52)
• macOS: Tahoe 26.1

Steps to reproduce

1. Click the Copilot for Xcode status bar button
2. Select Open Chat menu bar option
3. Type a message and click the Send button
4. Notice that there is no response or any loading indicators telling me that something is happening or Copilot is thinking or processing a response.

Logs
Bellow is a the log from my last attempt to send a message from ~/Library/Logs/GitHubCopilot/github-copilot-for-xcode.log:

Additional context
I'm using the enterprise plan, from my work MacBook Pro, and connected by Ethernet to the company network which as far as I know allows communicating with the service.

In the same machine and environment, I tried sending messages to GitHub Copilot plugin in Android Studio and it's working perfectly without any issues.

The issue with Copilot for Xcode seems to happen randomly (sometimes it works and other times it doesn't).

Let me know if there's any additional info you need.

Thanks!
