What's Wrong?

App version: 2.1.87
OS: macOS

Issue:
New sessions in the desktop app fail immediately with no response.
The log shows: Claude Code process exited with code 1

Running the binary manually reveals the actual error:
Error: Input must be provided either through stdin or as a prompt argument when using --print

The desktop app appears to be launching the claude binary with --print
but without passing the prompt, causing it to exit immediately.

Steps to reproduce:

1. Open Claude Code desktop app
2. Start a new session in any project
3. Type any message — no response, session fails immediately

Expected: Session starts and responds normally
Actual: Process exits with code 1, no response

Workaround: Using the CLI (claude in terminal) works fine.
