Antigravity IDE 2.5.5 Agent Fails Due to a Compatibility Issue with SentinelOne

For reference, I am still using Antigravity IDE version 1.23.2.

For some time, I could not determine why the agent stopped working whenever I installed Antigravity IDE 2.5.5. I have now identified what appears to be the cause.

Antigravity IDE 2.5.5 installs successfully. However, the agent fails because of a compatibility conflict between SentinelOne—the security software installed on my office PC—and Antigravity’s bundled language server.

The observed sequence is as follows:

  • Antigravity IDE 2.5.5 installs successfully.
  • The agent attempts to start language_server_windows_x64.exe.
  • SentinelOne injects InProcessClient64.dll into the language-server process.
  • The Go runtime encounters stack corruption.
  • The process reports: fatal error: unknown caller pc
  • The language server exits with code 2.
  • As a result, the IDE itself opens normally, but the agent does not respond.

I am not suggesting that SentinelOne itself is defective. More specifically, this appears to be a compatibility issue between SentinelOne Agent 24.1.5.277 and the language server bundled with Antigravity IDE 2.5.5.

Because this is a company-managed office PC, I cannot disable SentinelOne or modify its security policy myself. For now, I have uninstalled version 2.5.5 and returned to version 1.23.2, which still works.

Could the Antigravity team please investigate this compatibility issue or provide a supported workaround? If additional crash logs or diagnostic information are required, I would be happy to provide them.

Any help would be greatly appreciated.
