The user first launched his project and received an error on his HDD and UE4 crash with the default scene. He was able to open the project successfully a second time and opened the "Library Scene" (Content > Library) and worked fine. The user then tried to open the Hogwarts scene, (Content > Hogwarts > Hogwarts) and the Engine crashed. The engine crashes on each loading of the level.
The user thought it might have been caused due to his HDD, but the Engine runs successfully, and the user tried opening the scene on other computers as well and still received crashing.
