[BUG] Cowork doesn't run on Snapdragon processor
Resolved 💬 1 comment Opened Apr 22, 2026 by marcioandrade-glitch Closed May 27, 2026
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?
Hardware: Snapdragon X X126100 (Qualcomm Oryon CPU)
OS: Windows 11 Pro (ARM64)
Claude version: 1.3883.0.0 arm64
Error: VM connection timeout after 60 seconds / HcsShutdownComputeSystem: Invalid JSON document
Key finding: Daemon console log is 0 bytes — guest agent never starts after ARM64 boot
You can also mention that you spent significant time troubleshooting and that all prerequisites (Hyper-V, VM files, CoworkVMService) are confirmed working.
What Should Happen?
Cowork should start in my PC
