What happened?

Summary

When the model attempts to open the embedded browser in the right column from a conversation flow, the desktop app freezes on Linux (Ubuntu 24.04 x86_64). The freeze is hard and requires kill -9 to recover.

Environment

• OS: Ubuntu 24.04 (x86_64)
• Repository: github/app
• App context: GitHub Copilot desktop app (agent-native desktop experience)

Steps to Reproduce

1. Open the app on Ubuntu 24.04 x86_64.
2. Start/continue a conversation that triggers opening the embedded browser in the right column.
3. Wait for the embedded browser to initialize/open.

Expected Behavior

The embedded browser opens without blocking the app; the UI remains responsive.

Actual Behavior

The app freezes during/after the embedded browser open attempt.
Recovery requires force-terminating the process with kill -9.
Any try to produce a stacktrace were in vain.

Severity / Impact

High severity for Linux users: workflow interruption and forced process termination.
