I got this  
The referenced script on this Behaviour is missing!  
Assert in file: C:/BuildAgent/work/842f9557127e852/Runtime/mono/MonoBehaviour.cpp at line: 1341

How to solve that?

You added a Script as Component to a GameObject and then deleted or moved the file outside of the editor so it lost the reference. Click through your GameObjects and Prefabs and look for a missing reference to a script in the inspector.
