Assembly reload crashes when two different components on the same entity have identically named properties of different types

Release Type: Official Release

Version: 4.2.1.2442

Platform(s): Microsoft Windows 11 Pro 10.0.26100 x64

Describe the bug
Assigning an audio asset to a property on a custom EntityComponent causes Game Studio to crash during assembly reload. The crash happens while serializing the live object graph: UrlReference (and also Sound) is handled as if it were IIdentifiable, leading to an InvalidCastException. Game Studio closes as a result.

To Reproduce

• Create custom EntityComponent with UrlReference component.
• Attach the component to an entity in a scene/prefab.
• In Game Studio, assign any .xksnd audio asset to the property.
• Make a trivial code change and build (which triggers assembly reload).
• Game Studio crashes.

Expected behavior
It should be possible to use audio assets as properties on EntityComponents. Assigning a sound (via UrlReference or Sound) should survive assembly reload without crashing, and the assigned value should remain serialized/restored.

Log and callstacks

InvalidCastException: Unable to cast object of type
'Stride.Core.Serialization.UrlReference`1[Stride.Audio.Sound]'
to type 'Stride.Core.IIdentifiable'.

   at Stride.Assets.Presentation.AssemblyReloading.GameStudioAssemblyReloader...

Additional context
It does not matter whether the property type is Stride.Audio.Sound or UrlReference — both configurations crash Game Studio on assembly reload after assigning a value in the editor.

Start with the InvalidCastException path through Stride.Core.Assets.Serializers.IdentifiableObjectSerializer and Stride.Assets.Presentation.AssemblyReloading.GameStudioAssemblyReloader. Reproduce with UrlReference or Sound on an EntityComponent, assign an audio asset, and trigger assembly reload; done when the editor no longer crashes and the assigned value remains serialized and restored.
