Please help me solve this (standing on cube to pickup)

So I have reached a bump in the road, for the last 3 nights I have watched countless tutorials and read plenty of documentation. I have tried blueprint after blueprint. I am now starting from scratch again on this to have a blank canvas. I have created an image of what I am trying to create.

Player stands on a cube
Press E
cube goes away
player can run around
press E again
the cube appears back under them

see the attached image please

if someone can please help me create this mechanic I will gladly pay you.

Create an actor called CubeActor. Give it a static mesh and try this:-
It works for me.
