[BUG] Antigravity Agent stuck in infinite "Working..." state & background process hijacking Microsoft Edge

  1. Issue 1: Model Execution Deadlock (Stuck in “Working…”)
  • Description: When sending a prompt to the model/agent, it frequently gets stuck in a “Working…” state for upwards of 5 minutes before making any actual progress.
  • Behavior: This is not a slow LLM response issue, but an execution pipeline deadlock where the prompt isn’t even being dispatched/processed by the model until a long delay or timeout occurs.
  1. Issue 2: Terminal Execution Hijacking & Locking Microsoft Edge
  • Description: Spawning a terminal session within the Antigravity environment forcibly spawns/locks background Microsoft Edge (msedge.exe) processes.
  • Impact: This prevents the user from launching or using Microsoft Edge on the host OS. Even after manually terminating the msedge.exe process via Task Manager, a watchdog/guardian child process created by Antigravity immediately restarts it, causing persistent system resource conflicts.

Environment Details:

  • OS: Windows 11
  • Component: Antigravity IDE / Terminal Agent Executer

Hello @arcink

To resolve this deadlock and background process issue:

  • Please ensure that your Antigravity IDE and all associated agents are updated to the most recent version, as recent patches address execution pipeline deadlocks and process management bugs.
  • If the issue persists, can you provide any relevant console errors, IDE logs, or terminal output generated when the deadlock occurs?
  • Additionally, please share visual evidence of the agent stuck in the “Working…” state or the duplicated msedge.exe processes from your Task Manager.

We also recommend filing a direct bug report using the in-app “Report Issue” option so our engineering team can capture the necessary diagnostic data.
Let us know if the update resolves the problem.
