.NET MAUI app crashes when using InputKit with UraniumUI.Material

[aaronbarkan]

Describe the bug
Launching a .NET MAUI application that uses InputKit alongside UraniumUI.Material causes the app to crash due to an unhandled exception. The crash is triggered by a missing field: InputKit.Shared.Controls.PredefinedShapes.CheckCircle. This issue occurs on both Windows and Android (I have not tested on Mac and iOS).

Below are the exception details when launching the app on Windows:

System.Reflection.TargetInvocationException
HResult=0x80131604
Message=Exception has been thrown by the target of an invocation.

To Reproduce
Steps to reproduce the behavior:

1. Update Visual Studio to version 17.11.3 (Community Edition).
2. Create a new .NET MAUI project.
3. Install the InputKit 4.4.6 and UraniumUI.Material 2.9.1 NuGet packages.
4. Add InputKit and UraniumUI handlers to MauiProgram.cs.
5. Build and launch the app. Observe the crash.

Expected behavior
The app should launch without crashing.
