This problem is caused by the user script, it's an infinite recursive call.
The code that causes it in ConfigurationUtils.cs:
public static float BallImpulseForce
{
get
{
Debug.Log("There is no error here");
Debug.Log(BallImpulseForce); // <- this causes and infinite recursion (and eventually stack overflow)
return configurationdata.BallImpulseForce;

}
}

The correct code would be:
public static float BallImpulseForce
{
get
{
Debug.Log("There is no error here");
Debug.Log(configurationdata.BallImpulseForce); // <- no more recursive call
return configurationdata.BallImpulseForce;

}
}
