Title: Antigravity 2.0.11 crashes on startup with “GPU process isn’t usable. Goodbye.” (Windows 11, RTX 3070 Ti)

System:

  • Windows 11 (build 26200)

  • NVIDIA GeForce RTX 3070 Ti Laptop GPU

  • Intel Iris Xe Graphics

  • Antigravity 2.0.11

  • ASUS laptop

Problem:
Antigravity worked previously but now crashes immediately on startup.

Console output:

GPU process exited unexpectedly: exit_code=-2147483645
GPU process isn’t usable. Goodbye.

Additional log:

Starting app (v2.0.11) with dynamic port…
Spawning: language_server.exe …
GPU process exited unexpectedly: exit_code=-2147483645
FATAL: GPU process isn’t usable. Goodbye.

Troubleshooting already performed:

  • Uninstalled and reinstalled Antigravity.

  • Removed installation directory completely.

  • Tested launch with:

    • --disable-gpu

    • --disable-software-rasterizer

    • --use-angle=swiftshader

    • --disable-features=UseSkiaRenderer,Vulkan

    • ELECTRON_DISABLE_GPU=1

  • Ran SFC /SCANNOW (no integrity violations).

  • Ran DISM /RestoreHealth (successful).

  • Tested dGPU-only mode.

  • Stopped Overwolf processes.

  • Stopped Armoury Crate processes.

  • Tested older Antigravity 2.0.10 build.

  • language_server.exe starts successfully.

Observations:

  • VS Code works normally.

  • Chrome works normally.

  • Antigravity IDE works normally.

  • Only the standalone Antigravity application fails.

  • Aegis project files are intact and unaffected.

Request:
Please advise whether this is a known regression and whether there is a workaround, older stable build, or diagnostic logging option that can provide more information.
