### Current Behavior
Our MAUI project targets .NET 10 GA. We are currently using Community.Toolkit.MAUI version 9.0.3 . It works fine on iOS. When we upgrade the version to 13.0.0 (.NET 10 compatible as per the release notes of this version) app crashes on iOS with exception: error: Failed to load AOT module 'DotNetty.Buffers' while running in aot-only mode because a dependency cannot be found or it is out of date.
"
We use other packages like Microsoft.Azure.Devices, Microsoft.Azure.Devices.Client etc for communication with Azure.
It seems like the exception above coming from "DotNetty.Buffers" which is a transistive dependency of one of these 2 packages. Not sure why upgrading community.toolkit.MAUI to latest version causes crash due to these packages.
### Expected Behavior
App should not crash on iOS with 13.0.0 version of community.toolkit.MAUI.
### Steps To Reproduce
1. Open the solution from reproduction reposity and run it on iOS device.
2. Observe app crashing on launch.
### Link to public reproduction project repository

### Environment
```markdown
- .NET MAUI CommunityToolkit: 13.0.0
- OS: iOS 18.0
- .NET MAUI:10.0.10
```
### Anything else?

Research direction
Start with the linked SampleMCTCrash reproduction project and run it on an iOS device using .NET MAUI CommunityToolkit 13.0.0, then inspect the launch failure involving DotNetty.Buffers. Compare the working 9.0.3 setup with 13.0.0 and the Microsoft.Azure.Devices packages. Done means the reproduced app launches on iOS without the AOT loading crash.
