The Claude Code VSCode extension v2.1.136 (win32-x64) fails to activate entirely. All commands (e.g. claude-vscode.editor.openLast) show as "not found" because the extension crashes before registering any handlers.

Error Message

From %APPDATA%\Code\logs\<session>\window1\exthost\exthost.log:

[error] Activating extension Anthropic.claude-code failed due to an error:
TypeError: The argument 'filename' must be a file URL object, file URL string, or absolute path string. Received 'file:///home/runner/work/claude-cli-internal/claude-cli-internal/build-agent-sdk/sdk.mjs'
    at Module.createRequire (node:internal/modules/cjs/loader:1922:13)
    at Object.<anonymous> (c:\Users\..\.vscode\extensions\anthropic.claude-code-2.1.136-win32-x64\extension.js:103:5579)

Root Cause

extension.js line 103 contains a createRequire() call with the path file:///home/runner/work/claude-cli-internal/claude-cli-internal/build-agent-sdk/sdk.mjs — a hardcoded absolute path from the GitHub Actions build runner. That path does not exist on any user machine, so Node rejects it and the module fails to load.

Fix Action

Workaround

Downgrade to v2.1.133 via Extensions panel → "Install Another Version..." — confirmed working.

Impact

  • Extension does not activate at all on Windows
  • All commands unavailable
  • Reinstalling from the marketplace installs the same broken bundle — no workaround except downgrading

Steps to reproduce

  1. Install or auto-update to Claude Code v2.1.136 on Windows
  2. Open VSCode — extension silently fails to load
  3. Check exthost.log for the TypeError above

Environment

  • Extension version: 2.1.136 (win32-x64)
  • OS: Windows 11 Home 10.0.26200
  • VSCode: version at C:\Users\...\AppData\Local\Programs\Microsoft VS Code\8b640eef5a

Workaround

Downgrade to v2.1.133 via Extensions panel → "Install Another Version..." — confirmed working.
