Unreal Engine Issues and Bug Tracker (UE-45415)

Description

Qutting the engine with VR Editor on causes a crash. I could not determine a way to close the VR Editor internally so I terminated the Project by using the Desktop.

Many users among the community are also experiencing this crash.

Steps to Reproduce

Create a new project (No template or starter content needed)
Open the VR Editor
Close the Project (You cannot perform this action inside the VR editor, So You will need to close it from the Desktop)
Save all assets if asked

Result: The editor crashes
Expected Result: The Editor does not crash
