What's Wrong?

What's Wrong?

Claude Code process exits with code 1 immediately when launched from the Claude desktop app. Occurs on every prompt submission in every project folder (including fresh empty folders). Terminal-launched Claude Code 2.1.104 works perfectly with the same account, config, and auth state.

Environment

ProductName: macOS
ProductVersion: 26.3.1
ProductVersionExtra: (a)
BuildVersion: 25D771280a

• Desktop app bundled Claude Code: 2.1.111
• Terminal Claude Code (homebrew): 2.1.104 — WORKS FINE
• Node: v20 (also reproduced on v25)
• Account: Claude Max

What I tried (all failed to resolve)

• Downgraded Node 25 → Node 20 LTS via nvm
• Deleted ~/Library/Application Support/Claude/claude-code/ to force redownload
• Ran claude doctor directly on the bundled 2.1.111 binary — reports healthy
• Checked for Gatekeeper quarantine (none present)
• Verified ~/.claude.json and ~/.claude.json.backup are both valid JSON
• Disabled all plugins by resetting ~/.claude/settings.json to empty
• Confirmed terminal claude works in the same folder with the same config

Note

Terminal Claude Code at the homebrew-installed 2.1.104 works perfectly with identical config, auth, and project folder. Issue is specifically with the desktop-app bundled 2.1.111.

What Should Happen?

Claude code executes prompt
