[Bug]: Native chat rejects every Claude message ("Claude didn't accept this message") on 1.4.232; 1.4.230 works #31153

Operating system

macOS

Orca version

v1.4.232

Details

Summary

After Orca auto-updated from 1.4.230 to 1.4.232 (macOS, Apple Silicon), every message sent in a Claude native chat fails with "Claude didn't accept this message". Reinstalling 1.4.230 (Orca-1.4.230-arm64-mac.zip) fixes it immediately, with the same Claude Code install and config.

Environment

• macOS, Apple Silicon (arm64)
• Orca 1.4.232 (broken) / 1.4.230 (works)
• Claude Code 2.1.295 and 2.1.304 (native install) — both fail on 1.4.232
• Claude Team plan, usage well below limits

Steps to reproduce

1. Install Orca 1.4.232
2. Open any Claude native chat (existing or new, Opus or Sonnet)
3. Send any message, e.g. "oi"

Expected: Claude answers.
Actual: "Claude didn't accept this message" under every message.

What still works on 1.4.232

• claude in Orca's own terminal (interactive) answers normally
• claude -p "oi" --output-format stream-json --verbose succeeds (all SessionStart hooks exit 0, result is_error: false)

Ruled out

• Claude Code version (fails on both 2.1.295 and 2.1.304)
• Auth / account / rate limits
• Restarting Orca (Cmd+Q), opening brand-new chats, switching models
• Local plugins/hooks: no changes since before the update

Logs

• main.trace.ndjson: agentSession.startup reports outcome: "ready" for the chat; the message is rejected afterwards. No error span for the rejection itself.
• Renderer DevTools console: empty when the message is rejected.
• The chat spawns: claude -p --input-format stream-json --output-format stream-json --verbose

Timeline

• 08:49 (UTC-3): chat working on 1.4.230
• 09:38: auto-update to 1.4.232 applied (ShipIt)
• ~10:15 onward: every message rejected
• 11:27: reinstalled 1.4.230, chat works again
