BlazorWebView - grey screen on one machine #8461

Closed sgacond closed 2 years ago

sgacond commented 2 years ago

Is there an existing issue for this?

Describe the bug

Hi! I hope i'm on the right repo here, because I'm not sure if the error is caused in WebView2 or in the BlazorWebView control. Feel free to close and point me to the right repo if needed. Thanks in advance!

We use BlazorWebView hosted using the Win Forms Control (Microsoft.AspNetCore.Components.WebView.WindowsForms) and have issues on one particular machine. The app starts and doesn't load the WebView control (stays "system grey"). The application itself runs fine and (according to our logs) seems to work normally. Just the UI doesn't show up. DevTools aren't available either.

We already tried to reinstall the WebView2 runtime (Evergreen installer). Unfortunately no success.

Expected Behavior

BlazorWebView showing UI like on other machines.

Steps To Reproduce

Unfortunately it's not reproducable on other machines. Therefore I don't have a repro.

HostForm.cs constructor:

    public HostForm()
    {
        var serviceCollection = new ServiceCollection();

        serviceCollection.AddWindowsFormsBlazorWebView();

        // some other application related services...

        _serviceProvider = serviceCollection.BuildServiceProvider();

        var blazor = new BlazorWebView()
        {
            Dock = DockStyle.Fill,
            Padding = new Padding(0, 1, 0, 0),
            HostPage = "wwwroot/index.html",
            Services = _serviceProvider,
        };
        blazor.RootComponents.Add<Main>("#app");

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

Exceptions (if any)

Unfortunately no exception.

.NET Version

6.0.300 (self contained build fails on target machine - win-x64)

Anything else?

The issue persists on only this particular machine.

Is it possible to gather more information about this behaviour? I'm struggling finding logs or more information.

@sgacond thanks for contacting us.

I'm not sure how we could troubleshoot this. But I would start by using windbg to break on all thrown exceptions and see if there is a concrete exception that might be causing this.

You might also want to report this to the webview2 repo to see if they can offer you other tips to troubleshoot this.

sgacond commented 2 years ago

Hi @javiercn
Thanks for following up!

I ran the app using windbg and there are some exceptions in the command window. But windbg didn't break (tried "run until unhandled" and "run until handled"). Unfortunately, i'm not really used to this, sorry... windbg-log.txt

One is in Line 316+ after loading the WebView2 Loader:

There are also unregistered COM classes (Line 411+):

I also captured a memory dump of the process. Download Memory Dump The state of the dump is after showing the grey-screen.

javiercn commented 2 years ago

@sgacond could you inspect the exception when it happens? You should be able to get the exception name as well as the details.

sgacond commented 2 years ago

@javiercn I'm very sorry... I just fought against the preview and the "classic" version of windbg and was only able to get this: image I also built a debug-build including all symbols. Can you point me to a doc or something about getting the type of the CLR exception?

javiercn commented 2 years ago

@sgacond I had success in the past with https://www.sysadmins.lv/retired-msft-blogs/alejacma/managed-debugging-with-windbg-breaking-on-an-exception-part-1.aspx

I tried to unveil this "Unable to read memory at Address 0x97" by trying to read it after one more step over, but it seems to be out of scope then the debugger stopped (after configuration using the instructions in the link above).

Also with "dump object": image (same result on exception break and after one more step)

javiercn commented 2 years ago

@sgacond that's weird, what happens if you try to do !DumpObject

javiercn commented 2 years ago

The other thing that you can try is, once you are in that state, search for all the exceptions in the heap

sgacond commented 2 years ago

Unfortunately same result (just edited it in the answer above)

image (same result on exception break and after one more step)

sgacond commented 2 years ago

--- deleted

Ok... it was the wrong one. Sorry! Please disregard. This was the first break because of the log file. The second is the one causing the window to stop loading.

sgacond commented 2 years ago

This should be right break point now:

@sgacond do you see anything if you inspect _message or _innerException?

00205E5FB74283E8 011E5E5FB7428BE9 System_Private_CoreLib!System.BadImageFormatException..ctor(System.String, Int32)+0xb7428bea

Check that the bitness of the executable and the OS matches, or that the .NET installation in the machine is solid. You can try publish the app as self-contained too

@javiercn First of all, thanks again for your patience. I think I'm fishing in the dark and I was really unsure if I was inspecting the right exceptions.

So I tried to remove unnecessary things (squirrel update worker, logger, ...) that could lead to other exceptions.

After this, I did another clean self contained build (was self contained already) in debug mode. The bitness should be correct (--runtime win-x64), just checked system info again.

Now, windbg doesn't break anymore. Even with sxe clr and sxe 0xe0434f4d set. Therefore I suppose, there were no managed exceptions anymore.

But, the behavior stayed. So I breaked and looked at all the exceptions on the heap:

I think this is a textual search, therefore only the "real" exception are: ExecutionEngineException, StackOverflowException and OutOfMemoryException.

I tried to dump all three, but all with null pointers for _message or _stackTraceString:

I repeated the same step on my machine, where the exact same self-contained build runs just fine.

The Exceptions are here too. Therefore I think, the faulty behavior isn't visible in this Exception objects.

One more thing: I just recreated the most simple HelloWorld sample (according to this doc) and the issue persists.

Also the windbg behavior is the same. No break. Same three Exceptions on the heap: 

00007ff87aeef4b8        1          128 System.ExecutionEngineException
00007ff87aeef3b8        1          128 System.StackOverflowException
00007ff87aeef2b8        1          128 System.OutOfMemoryException

@sgacond thanks for the additional details.

You can discard stackoverflow and outofmemory exceptions. The runtime always allocates those two ahead of time, since it can’t allocate if it has no memory. I’m not sure about ExecutionEngineException, but it’s likely to be the case.

Could you create an app with just the webview (No blazor) and check if the issue still happens?

budcribar commented 2 years ago

It may help to catch the unhandled exceptions and perhaps you will get a hint from the error parameter

Add this to your main

AppDomain.CurrentDomain.UnhandledException += (sender, error) => { Console.WriteLine(error.ExceptionObject.ToString()); Console.ReadLine(); };

sgacond commented 2 years ago

Thanks for your hints! I just tried with two new samples:

The basic blazor one from above, but extended with a global unhandled exception handler (message box). ==> Same Result, no unhandled exception.

A basic WebView2 Hello World:

        public Form1()
        {
            var webView = new WebView2()
            {
                Dock = DockStyle.Fill,
                Padding = new Padding(0, 1, 0, 0),
                Source = new("https://mod-dotnet-bot.net/")
            };

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

==> Same here - works on my machine just fine, but on the target machine only system-grey. No exceptions. I think I have to move to the WebView repo.... Thanks for your support!

javiercn commented 2 years ago

@sgacond thanks for the additional details.

It seems that this is something at the webview2 level, I would suggest you file an issue in the webview2 repo here as they will be in a better position to help you.
