What's Wrong?

OS: Windows 11 Pro 24H2
Hardware: Lenovo Legion Pro 5 16IRX10, Intel i7-14650HX, RTX 5060, 16GB RAM
Claude Desktop version: [vezi în Help → About]

Issue: Clicking Cowork tab shows nothing. No error, no spinner, no UI.

Confirmed working:

• Hyper-V fully enabled (all features + Virtual Machine Platform + Windows Hypervisor Platform)
• bcdedit hypervisorlaunchtype = Auto
• CoworkVMService running
• vmcompute running
• vmms running
• Hyper-V Worker Admin logs confirm VM "cowork-vm-f28974d7" started successfully
• WSL2 works perfectly

Not working:

• Get-VM returns empty (VM disappears after start)
• %APPDATA%\Claude\logs folder does not exist
• UI never displays anything in Cowork tab

What Should Happen?

Claude Cowork should start from Claude desktop.
