You will probably need to provide more information than just, “game keeps crashing”
What version of the engine are you using?
Does UE4 crash while opening the editor, or when you are starting your game standalone, or do you have a blueprint being opened in the editor by default (i.e. you click on restore opened assests button)
if you create a new project (say the third person game, as a blueprint game) does that crash after creation? Before you do anything to it?
This should be the minimum amount of information needed, before anyone would have a chance at helping you.
