What's Wrong?

Bug:

Error from ~/Library/Logs/Claude/cowork_vm_node.log:

Error: Failed to create bridge sockets after 5 attempts
Process exited, code=1
macOS version: 15.7.4 (24G517)
Claude version: 2.1.111
Tried: restart app, check for updates, full Mac reboot — issue persists.

What Should Happen?

Cowork tasks should start and run normally. When a new task is created,
the Claude Code process inside the Cowork VM should initialize successfully
and respond to messages without crashing.

Error Messages/Logs

From ~/Library/Logs/Claude/cowork_vm_node.log:

[warn] [vm-stderr] Error: Failed to create bridge sockets after 5 attempts
[info] [Process] Exited, code=1, signal=null, duration=~1700ms, oom=false
[info] [Process] Cleaned up, remaining active=0

This error repeats on every attempt to start a task. 
The VM itself boots fine (network connects, SDK installs), 
but the Claude Code process crashes every time it tries to create bridge sockets.

Steps to Reproduce

1. Open Claude desktop app (Cowork mode)
2. Create a new task or open any existing task
3. Send any message
4. The process immediately crashes with "Claude Code process exited with code 1"

Tried the following without success:

• Restarted the Claude app (Cmd+Q and reopen)
• Checked for updates
• Full Mac reboot
