.NET MAUI 9.0 Preview 5 WinUI3中SkiaSharp用SwapChainPanel久用崩溃求助

我们在游戏GnollHack中使用.NET MAUI 9.0 Preview 5、.NET SDK 9.0 Preview 5及SkiaSharp 3.0 Preview 3.1，通过SkiaSharp的SKGLView结合SwapChainPanel在Windows/WinUI3上实现GPU加速图形渲染。程序初期运行正常，但一段时间后会崩溃，且该问题在Debug和Release模式下均会出现。

异常信息 #

Exception thrown at 0x00007FFB236EF39C (KernelBase.dll) in GnollHackM.exe: WinRT originate error - 0x80004005 : 'Reentrancy was detected in this XAML application.

复现步骤 #

• 按照项目Wiki的开发说明编译.NET MAUI Windows版本（编译操作较繁琐）
• 启动游戏并在设置中开启GPU加速，运行约10分钟后程序崩溃
