This issue seems not to be fixed for me : image

// webbrowser sample
private void loadWebBrowser()
{
    // webBrowser1 load local html file
    string html = "<html><body><h1>Sample HTML File</h1><p>First Sample paragraph.</p><p>Second Sample paragraph.</p></body></html>";
    webBrowser1.NavigateToString(html);
}

@neoxeo, Could you please attach the full project with the problem? Also copy/paste error text so I could translate it to English? I have checked the problem in ControlsTest project (test action "Navigate To String") and it works fine. Also is it IE or Edge?

Sorry, yes.

Here is error in english : image

System.AccessViolationException : 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Here is a testproject to reproduce error : testWebBrowser.zip

I run project from testWebBrowser.zip and it's fine. Used cmd: dotnet run --framework net8.0

So something could be with your Edge installation. Try to use IE backend. This call sets desired backend version WebBrowser.SetBackend(WebBrowserBackend value)

I will test this quickly. Strange thing is that navigate url works fine

After clean .nuget cache and generate new nuget packages with latest version, all works fine with Edge and IE.

I don't know what is the reason of error but now it is solve. Sorry.
