Critical Bug: Antigravity 2.0 instantly crashes on startup (Sandbox STATUS_BREAKPOINT)

Hi Antigravity Development Team,

I am reporting a critical startup crash with the Antigravity 2.0 IDE on Windows. When I launch the application, it loads for about 2 seconds and then silently terminates without showing any UI or error popups. Reinstalling the 2.0 did not fix the issue.

I ran some diagnostics with ELECTRON_ENABLE_LOGGING=1 and found that the underlying Chromium sandbox is violently rejecting the GPU process initialization.

Crash Details:

  • The Electron sandbox throws this error instantly on launch: [ERROR:content\browser\gpu\gpu_process_host.cc:999] GPU process exited unexpectedly: exit_code=-2147483645

  • It attempts to restart the GPU process 9 times in a fraction of a second.

  • It finally hits a fatal breakpoint and terminates: [FATAL:content\browser\gpu\gpu_data_manager_impl_private.cc:415] GPU process isn't usable. Goodbye.

System Environment:

  • OS: Windows

  • GPU: NVIDIA (Latest Drivers)

  • Antivirus: Windows Defender Only

  • Exploit Protection: Default (NOTSET across the board, no forced CFG)

  • Overlays: None (No Discord, MSI Afterburner, etc.)

Workarounds Tested:

  • Launching with --disable-gpu, --disable-software-rasterizer, and --disable-gpu-compositing failed (the sandbox still hit the exact same STATUS_BREAKPOINT and crashed).

  • Launching the shortcut with --no-sandbox successfully bypasses the crash and allows the to run perfectly.

Because this is a STATUS_BREAKPOINT (-2147483645) error that ignores standard GPU-disabling flags, it appears to be a deep OS-level Sandbox conflict in the version of Electron currently bundled with Antigravity 2.0. (I experienced the exact same sandbox crash with another Electron app, Wispr Flow, on the same machine).

I am currently using --no-sandbox as a temporary workaround to get my work done, but could you please investigate updating the Electron framework or pushing a patch to resolve this sandbox incompatibility?

Thank you!

Hi @isayak007 ,

Thank you for reporting this issue.

Recommended Solution: Update to the Latest Release

  1. Download the latest installer from the official Antigravity Download Page.
  2. Run the installer to update your current installation in place.
  3. Launch the application normally without the --no-sandbox flag to ensure the sandbox initializes properly with the updated runtime.

Additional Workaround & Troubleshooting (Cache Reset)

Beyond the flags you have already tested, if you experience any residual startup issues during or after the update, the Antigravity Troubleshooting Guide recommends clearing stale GPU and runtime caches:

  1. Close Antigravity completely.
  2. Open Windows Explorer (Win + R), paste %APPDATA%\Antigravity (or %APPDATA%\Antigravity IDE), and press Enter.
  3. Delete the GPUCache and Code Cache directories.
  4. Relaunch Antigravity.

Please let us know if updating to the latest build resolves the issue for you.
