Why is Unreal crashing? (FPS)

It seems like my engine is crashing, just by a simple command. :{

So, I am trying to make a a first person shooter, and apparently when I go inside the blueprint for the third person character (using Third Person project for starters) and try to:

  1. Scroll down on the components CRASH
  2. Try to drag the ‘FollowCamera’ component to the Mesh (Inherited) CRASH
  3. Clicking on anything expect for the view port CRASH

This is disappointing, as this is my first ever video game to create, and so far, this is becoming just dumb.

Please fix this problem, so your engine can be useable.
