What's Wrong?

Environment:

OS: Windows 11 Home 10.0.26200
Claude Code desktop app
Description:
The Cowork workspace consistently fails to start with the error: "VM connection timeout after 60 seconds". The issue persists after multiple restarts and workspace reinstalls.

Logs found in %AppData%\Roaming\Claude\logs\claude.ai-web.log:

MaxListenersExceededWarning: Possible EventEmitter memory leak detected.
11 CoworkScheduledTasks_onScheduledTaskEvent listeners added.
Use emitter.setMaxListeners() to increase limit.
This warning repeats continuously across sessions, suggesting event listeners are not being cleaned up between sessions, eventually causing the VM connection to time out.

Steps already taken (none resolved the issue):

Restarted Claude Code multiple times
Reinstalled the workspace multiple times
Verified network connectivity (Test-NetConnection api.anthropic.com -Port 443 → TcpTestSucceeded: True)
No proxy, no VPN
Windows Firewall reviewed — no blocking rules
Expected behavior: Cowork workspace starts successfully.

Actual behavior: VM connection times out every time. The CoworkScheduledTasks memory leak appears to be the root cause.
