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

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

extent analysis

TL;DR

The issue is likely caused by a compatibility problem with the latest Opus 4.7 update, and downgrading or waiting for a patch may resolve the bridge socket creation error.

Guidance

  • Verify that the error persists across different Cowork projects, including new ones, to confirm it's not project-specific.
  • Check the cowork_vm_node.log for any additional error details that might indicate a specific cause or dependency issue related to Opus 4.7.
  • Consider reaching out to the development team or community for any known issues or temporary workarounds related to the Opus update.
  • If possible, test the Cowork project on a different version of Claude Desktop to isolate if the issue is indeed version-specific.

Example

No specific code example can be provided without more details on the implementation, but checking the log files for patterns or specific error messages related to Opus 4.7 might look something like searching for Opus or bridge socket errors in the cowork_vm_node.log.

Notes

The exact cause of the issue is not specified, and without more technical details about the Opus 4.7 update or changes in the Claude Desktop version 1.3036.0, providing a precise fix is challenging. The issue seems to be related to the update, given that it started immediately after.

Recommendation

Apply workaround: Given the information, waiting for a patch or a fix from the developers might be the most straightforward approach, as downgrading might not be feasible or could introduce other compatibility issues.
