WebBrowser.Navigate(pdfPath) fails after WIN Update

Hi,
the last Microsoft Update
has broken the standard
WebBrowser.Navigate(pdfPath)
call, which allows to show a PDF preview within a Form.
I've been using this way for showing the preview because it worked easily for both x32 and x64 applications types.
Any suggestion for fixing it?
Please note that I'd like to keep that code and wouldn't implement this feature thru an alternative way (like using GhostScript).
T&R,
Piè

By the way, there is a modern WebView2 browser control, which corresponds to new Edge browser.

WebView2browser control.Thanks

It worked before...
but I just re-tested compiled as "x64", and I also get a grey box
(works as "Any CPU", tested on Windows 10 1909) -

I've implemented the WebView2 version.For doing it, I've followed the official MS guide: https://learn.microsoft.com/en-us/microsoft-edge/webview2/get-started/winforms
On my machine (the one I use for developing) it works like a charm.
However, I don't get how to make it working on another client.The guide speaks about prerequisites:
- https://developer.microsoft.com/it-it/microsoft-edge/webview2/
- https://www.microsoftedgeinsider.com/it-it/download
- .NET Framework version must be higher than 4.6
but I don't get if those are necessary for developing or running it.
Any idea?Thanks
