What's Wrong?

Environment

• Claude desktop app: v1.4758.0
• Claude Code binary: 2.1.119
• macOS: 14.1 (Darwin 24.1.0)

What happens
Every session started from the Code tab crashes in under 1 second with "Claude
Code process exited with code 1", no output. Has been broken since at least
April 19, 2026. Chat and Cowork (VM) sessions work fine.

Root cause identified
The desktop app passes two internal MCP servers — ccd_session and
ccd_directory — to the binary on startup. The binary tries to connect to these
IPC channels, fails immediately, and exits with code 1. From main.log:

[CCD] [replaceRemoteMcpServers] Calling SDK with 9 total servers {
serverNames: ['ClickUp', 'Google Drive', 'Slack', 'Claude in Chrome',
'mcp-registry', 'Claude Preview', 'ccd_session',
'ccd_directory', 'scheduled-tasks']
}
Session <blob> query error: Claude Code process exited with code 1
[CCD CycleHealth] unhealthy cycle (0s, hadFirstResponse=false,
reason=no_response)

After the crash, subsequent IPC calls fail:
[account] Account details not yet available, waiting for IPC...
[account] User logged out during IPC wait, stopping early

What confirms it's the IPC, not the binary
Running the binary manually with any combination of flags (including
--permission-mode acceptEdits, --setting-sources=user,project,local,
--plugin-dir, from the worktree directory) works perfectly. The binary only
crashes when the desktop app spawns it — the only untestable difference is the
ccd_session/ccd_directory socket arguments passed internally.
