The Claude code extension(v 2.1.52) or the latest version in VS Code is giving pop up "command 'claude-vscode.editor.openLast' not found" when clicked on "Claude Code: Open" button on the top right corner of the IDE.

Older versions don't have this issue.

Upon clicking on the "Claude Code: Open" button on the top right corner of the IDE(VS Code), a Claude chat window should open.

I encountered the same issue. Uninstall then reinstall didn't solve this for me, even after trying twice and reloading window. The CLI tool was still working and I asked it to diagnose the issue. It mentioned something about there being a hard-coded linux address, which was also mentioned in the prior bug report.

Finally got fixed by installing an older version of Claude Code 2.1.49

I encountered this issue with v2.1.53.

Uninstalling the extension and reinstalling it downgraded the version to 2.1.52; but it resolved the issue.

Thank you for your patience, v2.1.56 fixes the VS Code crash.
