What's Wrong?

The Cowork tab has disappeared from Claude Desktop on macOS after the app auto-updated to v1.1.7714. Cowork was working normally for several weeks prior to this build.
Root cause identified: The Cowork runtime is completely absent from the app bundle. Running:
ls /Applications/Claude.app/Contents/Resources/app.asar.unpacked/node_modules/ | grep -i cowork
returns nothing. The runtime was never packaged into this build.
Troubleshooting already completed:

Signed out and back in
Cleared ~/Library/Application Support/Claude and ~/Library/Caches/Claude
Fresh reinstall from claude.ai/download
Checked ~/Library/Logs/Claude/cowork_vm_node.log — log only shows module load with no VM boot attempt, no errors

Environment:

Version: 1.1.7714 (3bd6f6) 2026-03-19T14:50:53.000Z
macOS, Apple Silicon
Paid subscription (Cowork-eligible plan)

This appears to be a packaging regression. Related: #31647.

What Should Happen?

I would expect the cowork tab to show up and to continue working.
