This error is specific to using a vector - something is trying to call an index that is greater than the size of the vector. You should be able to to use .size() with a vector to try to avoid this. Note that if you are just straight up running the starter code, not everything is appropriately initialized (as that is part of the project), so it's unlikely to run without an error by default.
