Same issue here — Windows 11 ARM64, Surface Laptop Copilot+ (Snapdragon X)

Antigravity v1.20.5 — agent crashes on every request with: “Cannot call write after a stream was destroyed, Code -32099”

Unleash service fails to connect to localhost repeatedly. Agent starts responding then crashes mid-response. Displays “Antigravity server crashed unexpectedly. Reload.”

Tried everything:

  • Full uninstall/reinstall

  • Cache clear

  • Disabled PowerShell extension

  • Created GEMINI.md config

  • Cleared node_modules and logs

  • Tested Claude Opus and Sonnet — same crash

First request sometimes passes, second always crashes.

This is completely blocking my work. Please prioritize a fix for ARM64 Windows.
