Antigravity is not opening

The screen keeps loading but the app doesn’t open.

First specify your OS, because the fixes are slightly different for Windows and macOS.

If you are on Windows, make sure you actually installed both:

  • Antigravity IDE Kit

  • Antigravity itself

A lot of times the issue is not the install itself, but old cached updater files or broken background services staying in memory after failed updates. Their CI/CD and updater flow has honestly been pretty unstable recently.

Before doing anything complicated, try a complete reinstall once. Your chats/history usually stay synced to your account, so you normally will not lose your data.

You can also try clearing the old cache and stuck processes using PowerShell:

# Stop hanging Antigravity processes
Write-Host "Stopping all hanging Antigravity processes..." -ForegroundColor Cyan
Get-Process Antigravity, language_server -ErrorAction SilentlyContinue | Stop-Process -Force

# Remove junk XML temp files created by retry loops
Write-Host "Purging junk XML artifacts..." -ForegroundColor Cyan
Get-ChildItem -Path "$env:LOCALAPPDATA\Temp" -Filter "xml_file (*).xml" -ErrorAction SilentlyContinue | Remove-Item -Force

# Clear broken updater cache
Write-Host "Clearing stuck updater cache..." -ForegroundColor Cyan
if (Test-Path "$env:LOCALAPPDATA\antigravity-updater") {
    Remove-Item -Recurse -Force "$env:LOCALAPPDATA\antigravity-updater*" -ErrorAction SilentlyContinue
}

Write-Host "Cleanup complete! Ready for a clean reinstall." -ForegroundColor Green

Then reinstall the latest stable version manually instead of using the auto-updater.

If you are on macOS:

  • Fully quit Antigravity

  • Delete its cache from:
    ~/Library/Application Support/
    and
    ~/Library/Caches/

  • Then reinstall fresh

Also check whether Gatekeeper or security permissions blocked the app after install.

If it still refuses to open, then the best thing is to share the logs because most startup failures show there immediately.

Windows logs are usually somewhere around:

%APPDATA%\Antigravity\logs

macOS logs are usually around:

~/Library/Logs/Antigravity

Paste the startup logs or crash logs here if nothing works. That usually reveals whether it is:

  • broken updater loop

  • corrupted workspace

  • language server crash

  • permission issue

  • GPU rendering issue

  • or dependency failure
