Antigravity App not starting. "GPU process isn't usable."

Hi,

I have a problem, which I saw it was happening few months ago, but it’s persisting for me. Antigravity App is not starting at all.. Starting the app through Powershell leads to an error:
ERROR: GPU process exited unexpectedly: exit_code=-2147483645
FATAL: GPU process isn’t usable. Goodbye.

I’ve done a clean install and I downloaded and installed the latest version (2.14.0), but it’s not working. I have the latest Nvidia GeForce drivers, and my PC is up-to-date.
When I start the Antigravity.exe with --no-sandbox prop it works, but I don’t want to disable the sandbox environment..
Here are my specs:
GPU: NVIDIA GeForce RTX 2070 SUPER (8 GB)
CPU: AMD Ryzen 9 3900X 12-Core Processor (3.80 GHz)
RAM: 64 GB 2400MHz
OS: Windows 11 Pro 25H2
OS Build: 26200.9445

I’m using the Antigravity standalone IDE, and I don’t have a problem with it. Back when I installed the IDE I also installed the app, and it did worked, but I haven’t used it.. now I want to give it a try, but no luck.

Hi @ZPaskov,

To resolve the GPU startup issue without disabling the app sandbox via --no-sandbox, try the following steps:

  • Restore AppContainer Permissions & Clear Cache (Recommended)

    • This fixes the permissions that allow Antigravity.exe to utilize hardware acceleration securely.
      • Close any running Antigravity.exe or language_server.exe processes.
      • Open PowerShell and run the following commands to grant required read/execute access and clear stale GPU caches:
        • icacls "$env:LOCALAPPDATA\Programs\Antigravity" /grant "*S-1-15-2-1:(OI)(CI)(RX)" /grant "*S-1-15-2-2:(OI)(CI)(RX)" /T /C
          Remove-Item -Path "$env:APPDATA\Antigravity\GPUCache", "$env:APPDATA\Antigravity\DawnCache", "$env:APPDATA\Antigravity\Code Cache" -Recurse -Force -ErrorAction SilentlyContinue
          
      • Launch Antigravity normally.
  • If Step 1 fails due to a third-party GPU overlay or driver hooks (e.g., RivaTuner, NVIDIA overlays), you can selectively bypass the GPU sandbox while retaining workspace/renderer sandboxes.

    • Open or create the configuration file in PowerShell:
      • notepad "$env:USERPROFILE\.antigravity\argv.json"
        
    • Add the following JSON configuration:
      • JSON{
          "disable-gpu-sandbox": true
        }
        
    • Save the file and restart Antigravity.

Let me know is the issue resolves or the issue still persists!.
