Description
I have an issue with a BlazorWebView app, hosted in a WinForms application on one particular machine. We already discussed several loops and did some WinDBG runs together with the MAUI team: See issue on the MAUI-Repo.
But it turned out, a basic Hello World app with just a WebView2 Control shows the same behavior.

When starting the app, the window containing the WebView control stays "system-grey". No exception, no error message. I already tried to install another WebView2 runtime, but no change.

The issue persists just on this one machine.
I wasn't able to see exceptions or issues using WinDBG that aren't there on my machine (where the sample works fine).

            {
                Dock = DockStyle.Fill,
                Padding = new Padding(0, 1, 0, 0),
                Source = new("https://mod-dotnet-bot.net/")
            };

            InitializeComponent();
            Controls.Add(webView);
        }

In failing machine, could the edge run successful? Could you give some screenshots of the Taks manage, like:

I want to see if the msedgewebview2.exe has run.

Thanks for following up!

Normal edge runs just fine:

Sorry for long time no reply!
It seems like the webview2 processes are running.
Could you use spy++ to create a screenshot, I want to see if the WebView is hide.

I hope I chose the right window handle to inspect:

The browser process and render process has run, but from the spy++ cannot find the window handle, it is so strange, could you search the window with class Chrome_WidgetWin_1 to see if the windows exit.

Thanks @victorhuangwq for catching up!
Yes, the issue is still here. Just updated to 120.0.2210.133.
Still the same behavior.

I see, sorry that it's been a while. I'm wondering if there's anything specific / different about the machine that might be different your dev machine that might be a cause of this failure?

It's hard to say because the affected machine belongs to an Audio-Video professional with all kinds of software and low-level drivers installed. On the other hand, all "usual user fixes," like reinstalling WebView, trying different versions, etc., didn't help.
We have full control over the machine and are able to install / reinstall / uninstall stuff. But I don't know where to start.
