VS Code version: 1.117.0
OS: macOS (Apple M1 Pro)
Extension: GitHub Copilot Chat 0.43.0 (same with 0.44.2)
Description:
VS Code crashes completely (window terminated, reason: 'crashed', code: '5') approximately 40 seconds after connecting to a remote server via Remote SSH, when GitHub Copilot Chat is enabled.
Steps to reproduce:
Open VS Code 1.117.0 on macOS Apple Silicon (M1 Pro)
Connect to a remote Linux server via Remote SSH extension
Enable GitHub Copilot Chat and sign in
Wait ~40 seconds — observe "Codebase Semantic Index / Checking index status" spinner in the Copilot Chat panel
VS Code crashes entirely
Expected behavior: VS Code should not crash. Codebase indexing should either complete gracefully or fail silently.
Actual behavior: VS Code window terminates with code 5 (SIGSEGV) every time the codebase indexing starts.
Additional context:
The crash does not occur when launching VS Code with --disable-extension GitHub.copilot-chat
The crash does not occur when "Use AI Features" is disabled in Copilot settings
The crash does occur regardless of VS Code version (tested 1.116.0 and 1.117.0)
Removing ~/.vscode-server and reinstalling does not help
Setting github.copilot.semanticSearch.enabled: false and related settings in both local and remote settings.json does not prevent the crash
The Copilot Chat log shows WorkspaceChunkSearchService: using embedding type metis-1024-I16-Binary immediately before the crash
The renderer log shows ExperimentalWarning: SQLite is an experimental feature at startup
Workaround: Disabling GitHub Copilot Chat extension entirely prevents the crash, but makes Copilot Chat unusable.
