Fix for Claude VS Code Extension Error: 'command claude-vscode.editor.openLast not found'
The Claude VS Code extension version 2.1.51 has a bug that prevents it from loading properly, causing the error message "command 'claude-vscode.editor.openLast' not found" when users try to interact with it.
What's happening
Version 2.1.51 introduced a breaking bug that causes the extension to crash immediately on startup. This failure prevents the extension from registering its UI commands with VS Code. When users attempt to use the extension, VS Code throws the error because it can't find the registered commands.
The bug appears to be caused by a hardcoded path error in the extension's core files. According to reports, this issue largely affects Windows users.
How to fix it
To restore functionality while waiting for Anthropic to release a patch:
- Open the Extensions tab in VS Code
- Find "Claude Code" and click the gear icon ⚙️
- Click "Install Another Version..."
- Select version 2.1.49 from the dropdown list
- Reload VS Code
This downgrade to version 2.1.49 resolves the issue and returns the extension to normal operation.
