Class not registered 0x80040154 when using Gaussian blur

[rocksdanister]

Describe the bug

One of my users reports dialogs and settings menu not opening rocksdanister/lively#1496

I reported the original issue in WindowsAppSDK repo microsoft/WindowsAppSDK#3105

This time one of the error logs entries show CommunityToolkit:

2022-12-17 22:50:43.7049|ERROR|Lively.UI.WinUI.App|System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

I think I am experiencing the same issue. My app usesAcrylicBrush in one of its views and it's crashing only for one user who uses Windows 10 Enterprise LTSC. Here is the stack trace:

@Sergio0694 any ideas? I would assume this has to do with Win2D and possibly some down-level API support or something?

Can confirm, upgrading Microsoft.Graphics.Win2D to v1.2 fixed crashes on my side.

On release unpackaged published build of winui3 with the latest winappsdk v1.5.240428000 started getting TypeInitializationException with old version of Win2D library.

Thanks for confirming @rocksdanister, will close this issue then.
