Ubuntu 24.04.4 - Antigravity UI freezes after opening any folder (CodeWindow detected unresponsive)

Environment:

  • Antigravity Version: 1.23.2-1776332190
  • Ubuntu 24.04.4 LTS
  • X11 Session
  • Intel Iris Xe Graphics

Issue:
Antigravity launches and sign-in completes successfully.

However, after opening any folder (including an empty folder), the UI becomes completely unresponsive.

Observed behavior:

  • Explorer is visible.
  • Center editor never loads.
  • Right panel shows “Drag a view here to display.”
  • Mouse clicks stop working.
  • Menus become unresponsive.
  • Ubuntu reports “The window is not responding.”

What I tried:

  • Fresh Ubuntu installation
  • Fresh Antigravity installation
  • Fresh user profile
  • Disabled GPU
  • Disabled hardware acceleration
  • Disabled extensions
  • Empty folders
  • X11 session

Relevant log:
CodeWindow: detected unresponsive

Authentication completes successfully:
Auth state changed to: signedIn

Could you please help investigate this issue?

I am also facing the same issue on Ubuntu 22.04.5 LTS

hi the same thing happened to me and im using mint OS
so doing the following helped

remove the broken apt version

sudo apt remove antigravity

download the tar.gz from https://antigravity.google (Linux tarball)

cd ~/Downloads
tar -xvzf “Antigravity IDE.tar.gz”
sudo mv “Antigravity IDE” /opt/antigravity

fix sandbox permissions (required for Electron apps)

sudo chown root:root /opt/antigravity/chrome-sandbox
sudo chmod 4755 /opt/antigravity/chrome-sandbox

create a desktop launcher

cat << ‘EOF’ > ~/.local/share/applications/antigravity-ide.desktop
