What's Wrong?

Bug: Extension crashes on startup with "command 'claude-vscode.editor.openLast' not found" The extension fails to load when it can't find a previous session. Instead of gracefully handling this, it throws an unrecoverable error. Expected behavior: If session restore fails, prompt "Previous session not found. Start fresh?" and continue normally. Actual behavior: Extension is completely broken. User must manually delete globalStorage folder and reinstall. Fix required: Delete %APPDATA%\Cursor\User\globalStorage\anthropic.claude-code and reinstall extension. Environment: Claude Code 2.0.53, Cursor editor, Windows This is a basic error handling failure. The extension should never hard-fail because of missing local state.

What Should Happen?

Claude Code should start

A quick workaround that resolved this issue for me was to manually uninstall & reinstall the "claude-code" core package which is maintained by npm under node_modules.

1. run npm uninstall -g @anthropic-ai/claude-code or sudo rm -rf "$(npm config get prefix)/lib/node_modules/@anthropic-ai/claude-code" (to make sure it's removed).
2. run npm cache clean --force (to ensure npm pulls the latest build of claude-code)
3. run sudo npm install -g @anthropic-ai/claude-code
4. check if available through claude --version. If you have a native Claude CLI installation (e.g., via standalone installer), you may need to run the npm-installed binary directly to confirm: "$(npm config get prefix)/bin/claude" --version

Notice: Although this might fix the issue, this is still a workaround — we are still waiting for the core maintainers or developers of Claude Code to respond to this issue.

Please do not close this issue. This is a serious problem affecting multiple users. We would appreciate it if you could immediately investigate the root cause, or at the very least, acknowledge this issue and keep us updated on the progress. Thank you.
