SpeechToTextButton: ArgumentException is thrown when calling OnApplyTemplate() a second time

ArgumentException: WebView2 was already initialized with a different CoreWebView2Environment. Check to see if the Source property was already set or EnsureCoreWebView2Async was previously called with different values.

at Microsoft.Web.WebView2.Wpf.WebView2Base.EnsureCoreWebView2Async(CoreWebView2Environment environment, CoreWebView2ControllerOptions controllerOptions)
