1.0.2651.64

Start with a minimal WinUI3/WinAppSDK project in Visual Studio 2022 and reproduce the TypeLoadException after upgrading WebView2. Compare SDK versions 1.0.2651.64 and 1.0.2903.40, using runtime 131.0.2903.70 on Windows 11; done means identifying the compatibility cause and documenting a confirmed resolution.
