[~bgarcia], can you tell us what you mean by "empty" please? What do we need to do below to reproduce it? Because simply never setting the "url" or "html" property and closing the window doesn't crash it for me.
let navigationWindow = null; const parentWindow = Ti.UI.createWindow({ title: "Parent Window" }); const openButton = Ti.UI.createButton({ title: "Open WebView Window" }); openButton.addEventListener("click", () => { const childWindow = Ti.UI.createWindow({ title: "Child WebView" }); const webView = Ti.UI.createWebView({ // html: "", }); childWindow.add(webView); navigationWindow.openWindow(childWindow, { animated: true }); }); parentWindow.add(openButton); navigationWindow = Ti.UI.createNavigationWindow({ window: parentWindow, }); navigationWindow.open();
