}

public partial class MainWindow : Form

Ok, I got it. The reason is WebView2 Runtime not installed on user machine. I guess blazor should check WebView2 Runtime before start?

@wu-yafeng thanks for contacting us.

The webview package should already take care of that and surface a meaningful error. I suggest filing a bug in the webview2 repo if that's not the case.
