我安装了一些我认为导致问题的软件包：我安装了OneSignal和AppLinks，需要安装Xamarin.GooglePlayServices.Base和Xamarin.GooglePlayServices.Basement。然后Android特定包之间有一些冲突，我删除了我安装到OneSignal的所有软件包。我删除了bin和obj文件夹，干净并构建了项目，并重新启动了Visual Studio，但问题并没有消失！

Answer 1

事实证明，我安装了Intersoft Solutions的Crosslight.Xamarin.GooglePlayServices.Base软件包，被软件包名称误导，而我试图通过Microsoft下载软件包，我将其删除，现在项目正常运行
