Start by reproducing the launch failure and reviewing ~/Library/Logs/GitHubCopilot/github-copilot-for-xcode.log. Trace the CommunicationBridge, extension service, XPC service, and language-server startup entries; done means GitHub Copilot for Xcode.app stays open without the XPC service being interrupted.
