这是MAUI 8预览版。我可以看到同样的错误在AppCenter与OnePlus 8设备（Android 11），但我不能重现它.

Stacktrace：

Microsoft.Maui.Controls.Window.Microsoft.Maui.IWindow.Created()
Microsoft.Maui.LifecycleEvents.AppHostBuilderExtensions.<>c.<OnConfigureLifeCycle>b__2_0(Activity activity, Bundle bundle)
Microsoft.Maui.MauiAppCompatActivity.<>c__DisplayClass8_0.<OnPostCreate>b__0(OnPostCreate del)
Microsoft.Maui.LifecycleEvents.LifecycleEventServiceExtensions.InvokeLifecycleEvents[OnPostCreate](IServiceProvider services, Action`1 action)
Microsoft.Maui.MauiAppCompatActivity.OnPostCreate(Bundle savedInstanceState)
Android.App.Activity.n_OnPostCreate_Landroid_os_Bundle_(IntPtr jnienv, IntPtr native__this, IntPtr native_savedInstanceState)
Android.Runtime.JNINativeWrapper.Wrap_JniMarshal_PPL_V(_JniMarshal_PPL_V callback, IntPtr jnienv, IntPtr klazz, IntPtr p0)

解决方案

• 禁用MainActivity.cs/OnPostCreate方法
• 在try catch块中调用base.OnPostCreate(savedInstanceState)。
