Same here. Windows 11, Antigravity IDE v2.0.1, WSL Ubuntu 24.04. All 4 CDN URLs return 404 for Antigravity-reh.tar.gz. I also tried manually placing the old v1.107.0 server binary in ~/.antigravity-ide-server/bin/2.0.1-bf9a033f.../ — the server starts but the Extension Host crashes with exit code 55 (version mismatch: antigravityAnalytics service not found in old binary). The v2.0.1 Linux REH binary simply hasn’t been published to the CDN.
