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?

After updating Desktop App (Windows 11). On launch:
Failed to start Claude's workspace
failed to add Plan9 share 'x': HcsWaitForOperationResult failed with HRESULT 0x80310000: {"Error":-2144272384,"ErrorMessage":""}
Restarting Claude or your computer sometimes resolves this. If it persists, you can reinstall the workspace.
Windows 11 25H2 build 26200.8117, Claude Desktop v1.569.0.0, worked before update, fails at add_plan9_shares with HRESULT 0x80310000
What Should Happen?

Claude should install the plan to the VM
