What's Wrong?

After the Claude Desktop app auto-updated on March 20, 2026, Claude Code stopped responding in the desktop app. Messages are sent but no response is received, and the input field becomes disabled afterward.

Environment

• Claude Desktop version: 1.1.7714
• Claude Code (Desktop): 2.1.78
• Claude Code (Terminal): 2.1.80
• macOS: ARM64 (Apple Silicon)

Steps to Reproduce

1. Claude Desktop app auto-updated on March 20, 2026
2. Open Claude Desktop app
3. Start a new Claude Code session
4. Type any message and send
5. No response is received, input field becomes disabled

Error from Logs

Session local_XXXXXX query error: Claude Code process exited with code 1
[CCD CycleHealth] unhealthy cycle (0s, hadFirstResponse=false, reason=no_response)
[CCD] Passing 1 plugin(s) to SDK (skills: 1, local: 0)
← crash occurs immediately after passing skills plugin

Key Findings

• Terminal claude (v2.1.80) works perfectly fine
• Desktop app uses a bundled binary (v2.1.78) which crashes
• Crash occurs immediately after skills plugin is passed to the SDK
• Tried: reinstalling app, clearing all settings, deleting ~/.claude/, deleting claude-code-sessions, deleting skills-plugin cache — all failed
• The skills plugin folder is automatically re-downloaded and crash persists

Expected Behavior

Claude Code should respond normally in the desktop app as it did before the update.

Actual Behavior

Claude Code process exits with code 1 immediately upon session start when skills plugin is passed to the SDK.
