Consider using source generator

At the moment parts of your code base are using reflection to register your dialogs. eg

Moody.DialogService/Moody.DialogService/Services/DialogService.cs

Line 81 in afa3686

vm = Type.GetType($"{exportedType.FullName}ViewModel, {exportedType.Assembly.FullName}");

Consider using source generator similar to https://github.com/reactivemarbles/Splat.DI.SourceGenerator

Main advantage is performance.

Also the reflection code is a bit manual which can cause a bit of breakage easily

So with source generators btw, the actual code you produce isn't all that different, just you know the types at compile time and generate the code then.
