[BUG][Windows 11] Smart App Control blocks Antigravity startup on vscode-policy-watcher.node

Antigravity no longer reaches the home screen on Windows 11.

Environment

  • Product: Google Antigravity
  • OS: Windows 11
  • Smart App Control: ON
  • Launch method: normal launch and --disable-gpu both fail the same way

Observed behavior

  • Antigravity does not open its home screen
  • The startup fails because Windows blocks a native module at launch time

Blocked file
C:\Users\pc\AppData\Local\Programs\Antigravity\resources\app\node_modules@vscode\policy-watcher\build\Release\vscode-policy-watcher.node

Main startup error
Error: An Application Control policy has blocked this file.

Code Integrity / Smart App Control events

  • Event ID 3118: Smart App Control Block Details
  • Event ID 3077: Code Integrity determined that Antigravity.exe attempted to load vscode-policy-watcher.node that violated code integrity policy
  • Event ID 3033: Code Integrity determined that the file did not meet Enterprise signing level requirements

Policy info from logs

  • VerifiedAndReputableDesktop
  • Policy ID: {0283ac0f-fff1-49ae-ada1-8a933130cad6}

Important timeline

  • Antigravity was working earlier
  • At 2:41:40 AM Windows refreshed and activated Code Integrity policies
  • After that, every Antigravity launch attempt started failing

Request
Please investigate the signing / reputation / packaging of:
@vscode/policy-watcher/build/Release/vscode-policy-watcher.node

This currently prevents Antigravity from starting on Windows 11 systems with Smart App Control enabled.
