Hello and good day, let’s begin with the null reference, this happens when there is no object, field or variable that you have defined the class, component or game object within the code, the same debugger indicates which is the line to check for that context, I recommend that you verify and you make sure whether you need to create a prior reference to their use, sometimes you have to use something like this:

MyClass variableClass =  new MyClass();
//or something like this
RiggidBody riggid = gameObject.GetComponent<RiggidBody>();

Could be any type: Transform, Collider, Mesh, etc.

Check the documentation for more references, cheers. dO.o
