claude-code - 💡(How to fix) Fix [BUG] Cowork crashes with "Claude Code process exited with code 1" on every new session (macOS) [5 comments, 5 participants]

Every new Cowork session crashes immediately with the error "Something went wrong — Claude Code process exited with code 1." The message is sent, then the error banner appears and no response is returned. This started happening today; it was working previously.

Error Messages/Logs

1. Error banner appears: "Something went wrong — Claude Code process exited with code 1" The Claude Code process crashes instantly with exit code 1. The error banner offers "Go back" and "Try again" buttons, but retrying produces the same crash. [attach the screenshot of the error banner here]

TL;DR

The issue can likely be resolved by investigating and addressing the potential incompatibility or bug introduced in the latest version of Claude Code, possibly related to the Desktop App SDK flag or a regression.

Guidance

• Review the changes made in the latest version (Claude 1.3036.0) to identify any potential causes for the crash, especially focusing on updates related to the Desktop App SDK.
• Check the logs from ~/Library/Logs/Claude/ for any specific error messages that could indicate the root cause of the crash.
• Consider testing an older version of Claude Code to confirm if the issue is indeed a regression and to identify the last working version.
• Investigate the relationship between this issue and the mentioned GitHub issues (#46029 and #40540) to see if there are any common factors or solutions that could apply.

Example

No specific code snippet can be provided without more details on the internal workings of Claude Code or the Anthropic API. However, logging and debugging efforts should focus on the interaction between the Claude Code process and the Desktop App SDK.

Notes

The lack of specific error messages in the logs provided and the absence of a clear last working version make it challenging to pinpoint the exact cause. The issue's relation to previous bugs (#46029 and #40540) suggests that it might be part of a larger compatibility or regression problem.

Recommendation

Apply workaround: Given the potential for this to be a regression or compatibility issue, applying a workaround such as rolling back to a previous version of Claude Code (if possible) or awaiting a patch for the identified issues might be the most straightforward path to resolving the problem.
