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.

In each case the "cowork" tab is missing and In the last three updates I've caught, the following command returns empty:

ls /Applications/Claude.app/Contents/Resources/app.asar.unpacked/node_modules/ | grep -i cowork
