UWP/Unity: Unity crash when trying to instantiate the WebView as child or with scale zero

[ArDevKarl]

Description
I'm trying to use the WebView a child of a root object. Therefore I created a Prefab that contains the class "WebView" and its requirements. I want this Prefab to be instantiated as child of another transform and to be at scale = Vector3.zero on initialization.

The Prefab contains a helper class that handles all visial components. Here I want to setup the WebView as child and scale it:

private void Awake()
 {
     _webView = GetComponentInChildren<WebView>();
      _webView .transform.SetParent(root.transform); // <- causes crash
     _webView .transform.localScale = Vector3.zero; // <- causes crash

 }

If I maintain the scale and not change the parent of the WebView Unity or the application won't crash.

Version
WebView2: 0.17.1-pre.5
Unity: 2022.3.7f1

Repro Steps
Instantiate a WebView Prefab and try to change it's parent or scale it to zero.

Thanks for reporting the issue. @michaelfarnsworth could you please take a look?

@ArDevKarl I'd double-check that WebView control is ready. You can register a callback via WebView.GetWebViewWhenReady() or listen for the WebViewReady event. Hope that helps.

Ah thank you, that worked!

Please, make sure to throw an Exception everytime WebView is called while not ready.

@ArDevKarl Was this a request directed to the WebView2 team?

[victorhuangwq]

@ArDevKarl similarly, would you be referring to the Unity's WebView API in this request as well? If so, I would be closing this issue accordingly.

@victorhuangwq Like in the other post #3722 I'm talking about this:
https://learn.microsoft.com/en-us/windows/mixed-reality/develop/advanced-concepts/webview2-unity-plugin

I'll create a Feature Request about this issue.

EDIT: #3746

Hi @ArDevKarl,

Closing this issue since the feature request is being tracked in #3746. Thanks!
