Antigravity IDE chat interface not sending prompts for execution despite hitting Enter or Send Command: Fix

Hello Antigravity Team,

I encountered an issue where Antigravity IDE stops accepting prompts across all chat sessions on macOS.

Symptoms & Reproduction:

  • The chat prompt input becomes unresponsive.
  • Developer: Reload Window and Restart Extension Host do not clear the freeze.
  • Inference backend is alive, but local UI/daemon IPC communication is locked.

Root Cause:

  • After stream/network stalls, child processes (‘Antigravity Helper’, ‘language_server’) remain running in the background as orphans.
  • These orphan processes hold locks on IPC sockets/file descriptors, preventing new sessions from initializing clean RPC pipes.

Workaround that restores operation:

  • Quitting Antigravity IDE (Cmd + Q) and manually force-terminating ‘Antigravity Helper’ and ‘language_server’ processes in macOS Activity Monitor immediately fixes the issue upon relaunch.

Proposed Fix:

  • Implement a watchdog to ensure all child helper/daemon processes and socket descriptors are cleaned up upon application exit or reload.
