[Bug] Claude Code desktop app crashes on startup in Code mode with exit code 1

Bug Description

---

Claude Code desktop app (Code mode) crashes immediately with exit code 1 on every attempt. Terminal version works fine.

System: iMac 24-inch 2024, Apple M4, macOS Sequoia 15.7.5

Desktop app version: unknown (cannot access due to crash)

What was tried:

• Full disk access granted in System Settings
• Clean reinstall of desktop app
• Deleted ~/.claude and ~/.claude/projects
• claude auth logout and claude auth login (login succeeds, crash persists)
• Removed duplicate npm installation via sudo
• claude install (native 2.1.116 installed)
• claude doctor: no errors, single installation, OAuth auth confirmed
• macOS updated to 15.7.5
• which -a claude shows only one binary at ~/.local/bin/claude
• Console.app shows no crash logs when app fails

Observation: Chat mode in the desktop app works fine. Only Code mode crashes. Terminal version of Claude Code works perfectly.
