Use .Net 8.0 will make CommunityToolkit.WinUI.UI.Media crash always on WinUI3

[zhuxb711]

Describe the bug

Windows App SDK:
On .Net 7.0, everything works well. However, this exception will always throw on .Net 8.0 if using the AcrylicBrush

Exception: System.Reflection.TargetInvocationException
Message: Exception has been thrown by the target of an invocation.

Hello zhuxb711, thank you for opening an issue with us!

I think this is the issue related to the Win2D team. CommunityToolkit.WinUI.UI.Media 7.1.2 only require Microsoft.Graphics.Win2D >= 1.0.0.30, which is too old and released on 2021/11/17. So the solution is installing the Microsoft.Graphics.Win2D directly on your project to manually upgrade it to 1.1.1. Which solved this issue.
