I have a simple html:
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
</head>
<body>
<div id="tvchart"></div>
</body>
<script src="https://unpkg.com/lightweight-charts/dist/lightweight-charts.standalone.production.js"></script>
<script type="text/javascript" src="IndexWithMarkers6.js"></script>
<script>
function updateData(data) {
console.log(data);
}
</script>
</html>

I call the updateData in .NET: await webView.CoreWebView2.ExecuteScriptAsync("updateData('yyy')");, but the call is failed. How to do to call the function updateData?

On the test site, everything works correctly.

namespace WpfApp1test
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
        private async void Button_Click(object sender, RoutedEventArgs e)
        {
            await Xweb.CoreWebView2.ExecuteScriptAsync("updateData('yyy')");
        }
    }
}

So the problem is solely in your code.
