Unreal Engine Issues and Bug Tracker (UE-177367)

Description

After compiling a data asset blueprint, attempting to open the parent data asset will crash the editor.

From licensee: This is because in FAssetEditorToolkit::InitAssetEditor() the objects in ObjectsToEdit that are passed into a lambda `.IsEnabled_Lambda([ObjPtrsToEdit]()` and when it's called the object was collected. Using an array of TWeakObjectPtr (instead of UObject*) makes it possible to check if the object has been destroyed and the crash can be avoided.

Steps to Reproduce

Steps using attached example project:

Open DataAsset
Open DataAsset_Parent (while keeping DataAsset open)
Compile DataAsset_Parent
Select DataAsset editor tab, and observe editor will crash

Steps to repo without using attached example project:

Create a new primary data asset
Create a new data asset that is derived from the new primary data asset
Open data asset and its parent (primary data asset) in the asset editor
Compile primary data asset
Select data asset tab
