[BUG] Cowork "Virtualization not available" on ASUS TUF FX505DT — SVM Mode locked in BIOS

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

Cowork shows "La virtualización no está disponible — El espacio de trabajo de Claude requiere Virtual Machine Platform, pero el servicio de virtualización no responde" permanently. Restarting does not resolve it.
All Windows virtualization features are enabled (VirtualMachinePlatform, HypervisorPlatform, WSL, Hyper-V). The root cause is that the ASUS TUF FX505DT BIOS locks the SVM Mode option behind an Administrator password that cannot be set by the user, making it impossible to enable hardware virtualization from the BIOS. Related issues: #27316, #29887, #37265, #45715

What Should Happen?

Cowork should either detect that the issue is a BIOS-level SVM lock and display a clear message explaining this specific situation, or find an alternative way to initialize the workspace without requiring SVM Mode to be manually enabled in BIOS. On laptops where the BIOS Administrator password is locked by the manufacturer, users have no way to enable SVM Mode themselves.

Error Messages/Logs

La virtualización no está disponible. El espacio de trabajo de Claude requiere Virtual Machine Platform, pero el servicio de virtualización no responde. Reinicia tu computadora para resolver esto.

Steps to Reproduce

Install Claude Desktop (latest version) on ASUS TUF Gaming FX505DT with Windows 11 Pro
Enable all Windows virtualization features: VirtualMachinePlatform, HypervisorPlatform, Microsoft-Windows-Subsystem-Linux, Microsoft-Hyper-V-All
Run bcdedit /set hypervisorlaunchtype auto as Administrator and restart
Open Claude Desktop and navigate to the Cowork tab
Error "La virtualización no está disponible" appears immediately
Restarting does not resolve it
In Task Manager → Performance → CPU, Virtualization shows as "Deshabilitado"
Attempting to enable SVM Mode in BIOS (Advanced → CPU Configuration) is not possible — the option is greyed out and locked because the BIOS Access Level is "User" and the Administrator Password is locked by ASUS on this model

Additional Information

Device: ASUS TUF Gaming FX505DT-BQ624, manufactured 2020-07
CPU: AMD Ryzen 5 3550H with Radeon Vega Mobile Gfx
RAM: 8192 MB DDR4
BIOS Version: 316
The BIOS Access Level is locked at "User" on this model. The Administrator Password field is not accessible, making it impossible to elevate privileges to enable SVM Mode. This appears to be a manufacturer-level restriction on this laptop model.
Windows features confirmed enabled via PowerShell:

VirtualMachinePlatform: Enabled
HypervisorPlatform: Enabled
Microsoft-Windows-Subsystem-Linux: Enabled
Microsoft-Hyper-V-All: Enabled
