Bug Description

Clicking buttons on the Claude Code VS Code Extension UI results in the error:

command 'claude-vscode.editor.openLast' not found

Commands work fine via Command Palette (Ctrl+Shift+P → Claude: ...), but the Extension panel buttons fail with this error.

Steps to Reproduce

Install Claude Code VS Code Extension (v2.1.53)
Open VS Code
Click on the Claude Code extension panel/button in the sidebar
Click any button on the Extension UI
Error appears: command 'claude-vscode.editor.openLast' not found

Expected Behavior

Clicking the button should open the last Claude conversation in the editor.

Actual Behavior

Error: command 'claude-vscode.editor.openLast' not found

Environment

VS Code version: 1.109.5 (x64)
Extension version: 2.1.53
Claude CLI version: 2.1.53
OS: Windows 11 Pro 10.0.26100

Troubleshooting Attempted

Uninstalled and reinstalled the extension
Reloaded VS Code window (Developer: Reload Window)
Commands work via Command Palette but not via Extension UI buttons
Extension appears in Running Extensions list

Notes

The commands registered by the extension are accessible through the Command Palette, suggesting the extension activates partially but the UI buttons reference commands that are not properly registered or the activation event for those commands is not triggered.

I am experiencing the same error.

After a couple of hours going back and forth with Copilot I found the best workaround (for now) is to roll back to v2.1.52
