Hi @Ion.C,

Could you please follow these steps:

  • Kill all lingering background processes (ensure no background Antigravity/Node processes are running.)

    • Open Command Prompt (cmd) or PowerShell and run: 
      • taskkill /F /IM Antigravity.exe /T

taskkill /F /IM agy.exe /T

  • Clear the locked User Data and Cache folders

    • Press Win + R, paste each path below, and delete the folders (Antigravity will regenerate clean, non-elevated versions on launch):
      • %APPDATA%\Antigravity (Main IDE state, session locks, and Chromium cache)
      • %USERPROFILE%\.gemini\antigravity-ide (Workspace/brain cache)
    • If Windows prevents deletion because files are “owned by Administrator”, right-click the folder > Properties > Security > Advanced to take ownership, or delete it via an elevated Command Prompt: rmdir /s /q "%APPDATA%\Antigravity"

  • Verify Shortcut Compatibility

    • Right-click the Google Antigravity shortcut and select Properties.
    • Navigate to the Compatibility tab.
    • Ensure “Run this program as an administrator” is UNCHECKED.
    • Click Apply and OK.

  • Launch Antigravity as a Standard User

    • Launch the app normally from your Start Menu without right-clicking “Run as Administrator”.

If the UI still hangs on the splash screen, test launching with a temporary user directory to isolate any lingering GPU/hardware cache locks:

Press Win + R and run: "%LOCALAPPDATA%\Programs\Antigravity\Antigravity.exe" --disable-gpu --user-data-dir="%TEMP%\antigravity-fresh" (Adjust the executable path if installed in C:\Program Files.)

If you are still seeing the loading screen after completing these steps, could you please share the logs :%APPDATA%\Antigravity\logs.

I’m experiencing the same issue. The agent remains stuck on
“Loading” and does not generate anything. I already tried
completely uninstalling and reinstalling Antigravity,
including removing all configuration files, caches, and
credentials, but the problem persists.

The logs show:

  • state syncing error: key not found
  • Failed to get OAuth token
  • Failed to get CAIC project
  • failed to get loadCodeAssistResponse

The Google login completes successfully, but the language
server cannot retrieve the OAuth token afterward.
