GPU process exited unexpectedly: exit_code =-532462766

I tried to use a cefsharp in a WPF application to show a PDF file.
After I set the Address to the PDF location.
I got the following error message.

Can someone help me out on this problem?
Many thanks.

How does the WPF example behave? https://github.com/cefsharp/CefSharp.MinimalExample

[tracyfhy]

No.
Actually the situation is, I want to add cefSharp to an existing and complicated console application (APP COM) to display a PDF file.
So at first, I tried cefSharp in a very simple testing console application (APP TEST), and it worked.
Then I tried to merge the function I tested in APP TEST into APP COM, then the error appeared.
Neither APP TEST and APP COM had such file "app.menifest".

This information should have been provided initially.

It's possible that the browser is unable to correctly locate CefSharp.BrowserSubprocess.exe, try manually specifying the path

var settings = new CefSettings()
{
	//By default CefSharp will use an in-memory cache, you need to specify a Cache Folder to persist data
	CachePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "CefSharp\\Cache"),
	BrowserSubprocessPath = "Absolute path to CefSharp.BrowserSubprocess.exe"
};

Cef.Initialize(settings, performDependencyCheck: true);

Make sure to call Cef.Initialize on the WPF UI Thread before creating your first ChormiumWebBrowser instance. See https://github.com/cefsharp/CefSharp/wiki/General-Usage#initialize-and-shutdown for more detail.

Neither APP TEST and APP COM had such file "app.menifest".

It is always recommended that applications have an app.manifest, it's not something CefSharp specific.

[tracyfhy]

I changed the code as suggested to both APP TEST and APP COM. Nothing changed. APP TEST worked and APP COM failed.
I debugged the code. It the code actually crashed at:
cefBrower.UpdateLayout();
cefBrower is the browser.
I used this because the address of cefBrower need to be specified after the initilization.

BTW, after compiling APP COM, there were only CefSharp.Core.xml, CefSharp.Wpf.xml, and CefSharp.xml.
There was no such files as CefSharp.dll, CefSharp.dll, CefSharp.dll

Copy the files manually, confirm your app works.

I'll need a better description of your project structure. APP COM doesn't really tell me much.
