Creating a blueprint from selected components crashes editor if components contain a blueprint with a component

Frequency: 2/2
Crash Reporter: [Link Removed]

Editor crashes if the option: "Convert Selected Components to Blueprint Class" is selected from main editor viewport>Blueprints context menu. This occurs if one of the components is a blueprint that contains a component.

1. Open Editor (any project)
2. Create a new blueprint of type actor
3. In blueprint, add a static mesh component
4. Place a copy of blueprint into level viewport
5. Place a cube (modes>placement>basic>cube) into level
6. Select both cube and blueprint in level viewport
7. Open Blueprint context menu>Convert Selected Components to Blueprint>Ok

Results:

Editor crashes

Expected:

New blueprint is containing that contains a child actor component of the blueprint class and a cube component.
