WPF JumpList图标无法正常显示问题求助

我在WPF应用中配置了JumpList，功能整体可正常运行，但图标无法显示。

以下是创建JumpTask的代码：

using System.Windows.Shell;

public JumpTask BuildJumpTask
{
    get
    {
        return new JumpTask
        {
            Arguments = Argument,
            ApplicationPath = Assembly.GetEntryAssembly()?.Location,
            Description = GenerateDescription(),
            IconResourcePath = GetIconPath(),
            Title = Name
        };
    }
}

private string GetIconPath()
{
    return Type switch
    {
        JumpListItemType.About => Path.GetFullPath(@"Assets\Icons\JumpList\About.ico"),
        JumpListItemType.Help => Path.GetFullPath(@"Assets\Icons\JumpList\Help.ico"),
        JumpListItemType.Quit => Path.GetFullPath(@"Assets\Icons\JumpList\Quit.ico"),
        JumpListItemType.Settings => Path.GetFullPath(@"Assets\Icons\JumpList\Settings.ico"),
        JumpListItemType.Sign_Out => Path.GetFullPath(@"Assets\Icons\JumpList\Sign_Out.ico"),
        _ => null!
    };
}

所有.ico文件已输出至预期目录，文件属性设置如下：

• Build Action: Embedded resource（也尝试过Content）
• Copy to Output Directory: Copy if newer
