What's Wrong?

Failed to create bridge sockets after 5 attempts. Cowork is unuseable after today's update (which included Opus 4.7)

What Should Happen?

Cowork projects shouldn't throw an immediate error. It should create the bridge sockets.

Error Messages/Logs

Desktop version: 1.3036.0
Error from ~/Library/Logs/Claude/cowork_vm_node.log:
[vm-stderr] Error: Failed to create bridge sockets after 5 attempts
Process exited, code=1, duration=~900ms
Affects: All Cowork projects including brand new ones. Started after today's Desktop update. Chat and Claude Code unaffected.

Steps to Reproduce

Based on what I've experienced today:

Update Claude Desktop to version 1.3036.0
Open any existing Cowork project
Observe "Claude Code process exited with code 1" immediately

Or for a clean repro:

Update Claude Desktop to version 1.3036.0
Create a brand new Cowork project
Observe the same error on first launch
