Reproduction Steps

    {
        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);
            CefSharpSettings.RuntimeStyle = CefRuntimeStyle.Chrome;
        }
    }

public partial class MainWindow : Window
    {
        ChromiumWebBrowser browser;
        public MainWindow()
        {
            InitializeComponent();
            var url = @"chrome-extension://ophjlpahpchlmihnnnihgmmeilfjmjjc/index.html";
            RequestContextSettings contextSetting = new RequestContextSettings()
            {
                CachePath = @"C:\Users\pc\Desktop\demo\demo_team\demo\bin\x64\Debug\net6.0-windows\data\chrome_user\user_data_1",

            };
            var requestContextBuild = RequestContext.Configure();
            requestContextBuild.WithSharedSettings(new RequestContext(contextSetting));
            browser = new ChromiumWebBrowser(url, requestContextBuild.Create());
            fromHost.Child = browser;
        }
    }

Expected behavior

When I set CefSharpSettings.RuntimeStyle = CefRuntimeStyle.Chrome; and load the Line extension, there is a chance that a Chrome error window will pop up with the error code: STATUS_ACCESS_VIOLATION.
