What's Wrong?

Claude desktop shows "requires a more recent installation" message even after a fresh reinstall of the latest version (1.13576.0) when I want to switch to Cowork. The Cowork tab is inaccessible. A colleague on the same version faces the same issue.

What Should Happen?

After installing the latest version of Claude for windows, Cowork should be accessible without prompting for reinstallation.

Error Messages/Logs

No error log surfaced. The app displays a dialog: "Cowork requires a more recent installation. Reinstall the desktop app to access Cowork and start delegating longer tasks." with a "Reinstall" button. Clicking it and reinstalling does not resolve the issue.

Steps to Reproduce

1. Download and install the latest Claude Code for Windows from claude.com/download
2. Open the app and navigate to the Cowork tab
3. A dialog appears: "Cowork requires a more recent installation"
4. Click "Reinstall", download and reinstall the app
5. Reopen the app — the same dialog appears again

This is NOT a duplicate of the yukonSilver VM issues. My problem is different:
no VM error appears, the app simply shows "requires a more recent installation"
despite running the latest version (1.13576.0) on a fresh install.
No CoworkVMService or Hyper-V involvement.

Describe the bug
Cowork was working normally on this PC and stopped working without any manual update.
Now it shows the message "Cowork requer uma instalação mais recente" (Cowork requires a more recent installation).

Steps to reproduce

1. Open Claude desktop app
2. Try to access Cowork
3. Message appears: "Cowork requires a more recent installation — Reinstall the desktop app to access Cowork and start delegating longer tasks"

Expected behavior
Cowork should work as it did before.

Current behavior

• Reinstalled the app 21+ times — same version is installed every time
• The auto-updater checks for updates and finds none
• Version 1.14271.0 appears to be the only version available for this device

Environment

• OS: Windows 11 Pro (10.0.22621)
• App version: 1.14271.0
• Device ID: c1a19348-70e7-4013-aa30-6e0d3f70e601
• Staging user ID: a9e906dc-a593-5822-aa42-ab9703aa5994

Additional context
The buddy-tokens.json file exists confirming Cowork was used previously on this machine.
The Squirrel updater connects to the server but receives no newer version for this device_id.
