What's Wrong?

When installing Claude Cowork, the VM boots at HCS layer but daemon console log is completely empty. Linux guest never reaches userspace and vsock connection times out after 60 seconds on every attempt. I am using OS: Windows 11 on ARM64 (build 10.0.26200.8037). Levovo IdeaPad Slim 3 with Snapdragon processor. Claude version 1.1617.0.0 (ARM64).

What Should Happen?

VM should boot, Linux guest should reach userspace and vsock should not timeout.

Error Messages/Logs

Vsock timeout after 60 seconds.

Steps to Reproduce

As above. Seems to be related to specific platform after installing Claude.
