Start with the bicep.lsp-error report and the extension.js call stack in the issue, then try to reproduce it in Claude Code Planning mode on Windows with Bicep 0.41.2 and VS Code 1.110.0. Done means the connection-closed cause is identified and the issue has a verified resolution or a documented non-reproduction.
