Unreal Engine Issues and Bug Tracker (UE-72316)

Description

When duplicating multiple components at once it appears to crash the editor.

Regression: Yes, this appears to be working in the previous version of the engine (4.21.2-4753647)

Steps to Reproduce

Open the editor
Create a new actor blueprint
Add a component to the blueprint (static mesh was used in this example (should end up being default scene root > static mesh))
Select both components
Press ctrl+W or right click > duplicate

Result: The editor crashes
Expected: The selected components would be duplicated
