Webview does not work on linux

My sample app was working fine on windows, but not on linux.
While in debugging, the WebView constructor will hang and not go back.
```C#
using AvaloniaWebView;

WebView webView = new WebView();  // <- this line will not return.
```
This case my app renders an empty window.

OS: Ubuntu 24.04
C# 8.0
Avalonia 11.3.0
