What's Wrong?

Hi Anthropic Support,

Cowork started failing on every task mid-day today (April 16, 2026), after working normally for the past month. Looking for help resolving.

Error: "Something went wrong. Claude Code process exited with code 1. You can restart the conversation from an earlier message."

Behavior:

  • Occurs immediately on every task, new or existing
  • "Try again" hangs indefinitely on "Reconnecting..."
  • "Go back" + resend reproduces the same error
  • Reproduces on both Opus 4.6 and Opus 4.7
  • Status page shows Cowork as Operational, so this may be account- or client-specific

Environment:

  • MacBook Pro, macOS Apple M4 Pro
  • Cowork app version Claude 4.6 then Claude 4.7
  • Most recent failure: 11:30 ish PST Already tried (none resolved it):
  • Cmd+Q and relaunch
  • Multiple new tasks
  • Switching between Opus 4.6 and Opus 4.7
  • Sign out / sign in
  • Laptop restart

Happy to send screenshots of the error and the reconnecting loop, pull logs, or run any diagnostic you need.

Thanks, Kevin Keranen

What Should Happen?

It should take over my computer and complete the instructions I sent via computer use in Cowork

extent analysis

TL;DR

The issue may be related to a regression in the Claude Code version, and trying to revert to the previous working version, Claude Opus 4.6, could potentially resolve the issue.

Guidance

  • The error message "Something went wrong. Claude Code process exited with code 1" suggests a problem with the Claude Code process, which may be specific to the account or client.
  • Given that the issue started after working normally for a month and the status page shows Cowork as Operational, it's possible that the problem is account-specific or related to a recent change.
  • Trying to reproduce the issue on a different device or environment could help determine if the issue is device-specific.
  • Since the user has already tried switching between Opus 4.6 and Opus 4.7, and the issue persists, it may be worth investigating if there are any account-specific settings or configurations that could be causing the issue.

Example

No code snippet is provided as the issue seems to be related to a specific version or configuration of the Claude Code.

Notes

The issue may be related to a regression in the Claude Code version, but without more information about the changes made between versions, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Try reverting to the previous working version, Claude Opus 4.6, to see if the issue resolves. This is because the user has mentioned that the issue started after working normally for a month, and the previous version was working correctly.
