I dont really know where to put this topic but this seemed to be the most fitting place.
I am relatively new to the Unreal Engine 4 and made a mistake the other day:
I wanted to delete a cube off my Project but instead I deleted the cube off the whole Game Engine. Now, every time I open the UE4 the message below appears and I cannot spawn a Cube anymore.
Is there any way, exept for reinstalling the Engine, to fix this?
