var options = new CoreWebView2EnvironmentOptions();
var environment = await CoreWebView2Environment.CreateAsync(string.Empty, userDataFolder, options);
var controllerOptions = environment.CreateCoreWebView2ControllerOptions();

Unable to cast to Microsoft.Web.WebView2.Core.Raw.ICoreWebView2Environment10.
This may happen if you are using an interface not supported by the version of the WebView2 Runtime you are using.
For instance, if you are using an experimental interface from an older SDK that has been modified or removed in a newer runtime.
Or, if you are using a public interface from a newer SDK that wasn't implemented in an older runtime.

I've recently had the same issue. I have two applications, one .NET Framework, one .NET. The .NET one seems to work fine with the same library version (both reference Microsoft.Web.WebView2 1.0.2651.64) but the .NET Framework code base fails with the same message on the same method.

The ICoreWebView2Environment10 interface is not exactly new so I doubt this is due to using some preview release. I can confirm that the .NET Framework code base that fails now worked a few weeks ago.
