What happened?

In Winfrom or WPF Project,when using System.Windows.Forms.OpenFileDialog on a Razor page, an exception is thrown after waiting about 30 seconds after the dialog pops up: System.Runtime.InteropServices.SEHException: "External component has thrown an exception."
The demo project is located at this address:
https://github.com/mmgdh/TestFileDialog.

I have submitted an issue on WPF, and they tested it and found that the exception occurs in EmbeddedBrowserWebView
