[Linux][Ubuntu 24.04][v1.107.0] Language Server crashes immediately with CRNGT failed (SIGABRT) on AMD Ryzen 5 3450U

Hello Antigravity Engineering Team,

I would like to report a reproducible Linux issue where the Antigravity Language Server crashes immediately during startup, preventing all AI functionality from working.

Environment

Operating System

  • Ubuntu 24.04 LTS
  • Kernel: 6.17.0-35-generic

CPU

  • AMD Ryzen 5 3450U with Radeon Vega Mobile Graphics
  • CPU flags include:
    • AES
    • AVX
    • AVX2
    • SSE4.1
    • SSE4.2

Antigravity

  • Version: 1.107.0
  • Installed from the Linux tarball release.

Problem

The IDE launches successfully.

However, immediately after startup, the following message appears:

“Antigravity server crashed unexpectedly. Please restart to fully restore AI features.”

The editor remains usable, but every AI feature is unavailable because the bundled Language Server terminates during initialization.


Investigation Performed

I performed a detailed investigation before reporting the issue.

Verified items

  • Electron launches correctly.
  • Renderer process starts correctly.
  • Extension Host starts correctly.
  • .gemini directory permissions are correct.
  • GNOME Keyring is installed.
  • libsecret is installed.
  • User configuration is writable.
  • CPU supports AES, AVX and AVX2.
  • Running with --no-sandbox does not change the Language Server behavior.
  • Running the Language Server directly reproduces the same crash without Electron involvement.

Language Server Output

Running the bundled binary directly:

language_server_linux_x64

Immediately produces:

CRNGT failed.
SIGABRT: abort
signal arrived during cgo execution

The stack trace shows the abort occurring during cryptographic initialization:

crypto/internal/boring._Cfunc__goboringcrypto_RAND_bytes
crypto/internal/boring.randReader.Read
crypto/rand.Read
google3/third_party/golang/github_com/getsentry/sentry_go/v/v0/sentry.NewPropagationContext

The Language Server exits before initialization completes.


Antigravity Logs

The IDE reports:

Language server exited with code 2
Failed to start language server:
Language server exited before sending start data

Additional Information

The bundled Language Server appears to include Go’s FIPS/BoringCrypto implementation.

Using strings on the binary shows references such as:

crypto/fips140.setBypass
crypto/internal/boring

This suggests the crash occurs during initialization of the bundled cryptographic runtime rather than in the Electron application itself.


Sandbox

Running the main executable without --no-sandbox produces the expected Linux portable tarball sandbox error:

chrome-sandbox is not configured correctly

This is separate from the Language Server issue.

Even when using --no-sandbox, the Language Server still aborts with the same CRNGT failed error.


Observations

From my investigation, the issue appears isolated to the bundled language_server_linux_x64 binary.

The Electron application itself starts normally.

The failure occurs before the Language Server sends its startup handshake, indicating that it aborts during early initialization.


Request

Could you please confirm:

  1. Whether this is a known issue affecting Linux builds of Antigravity 1.107.0.
  2. Whether there is a patched Language Server binary available.
  3. Whether there are any known issues involving Go FIPS/BoringCrypto initialization on AMD Ryzen systems.
  4. If additional diagnostic logs or core dumps would be useful, I would be happy to provide them.

Thank you for your time, and I appreciate your work on Antigravity.
