Title: Cowork stuck on "Setting up Claude's workspace" — Windows 10 Pro, latest version
Description:
Environment:

OS: Windows 10 Pro
Claude Desktop version: 1.1.8359 (64248d)
Subscription: Pro
Hyper-V: Enabled

What's wrong:
Cowork is permanently stuck on the "Setting up Claude's workspace" loading screen. It never completes and shows no error message.
What I tried:

Enabled Hyper-V via PowerShell (was Disabled, now Enabled)
Restarted the computer
Cleared cache via Help → Troubleshooting
Full uninstall and reinstall of Claude Desktop
Verified Windows Firewall allows Claude on both Private and Public networks
Updated to the latest version (1.1.8359)

Nothing has resolved the issue. Cowork has never successfully initialized on this system.
Expected behavior:
Cowork should complete setup and be ready to use.
