Windows平台MAUI Shell导航随机崩溃问题求助

• 测试场景：搭建简易MAUI项目，MainPage绑定MainPageViewModel，通过按钮或手势触发相对路由导航至SelectPage（保留导航栏返回按钮）
• 异常表现：反复在两页面间切换时，随机触发未处理的Microsoft.UI.Xaml.Controls.Frame.NavigationFailed异常，崩溃时机无规律；但用ScreenToGif录制操作时，第二次导航必然崩溃。崩溃前会先抛出System.Runtime.InteropServices.COMException异常
• 简化验证：已将项目精简到仅保留MainPage的按钮和SelectPage的标签，问题依然复现；关键发现：若SelectPage的根ContentPage内没有任何元素，不会出现崩溃，但只要添加一个简单Label，崩溃就会复现

异常堆栈跟踪：
