Chief Delphi - CAN Transmit Error and standard output

I have created a function that calculates the I part of PID and then outputs the data to the console to create a graph and analyze different constants (Ki). This is a side project while we wait on build to finish what they are working on. The integral function works, but when I add it to our Sample Robot, it fails for multiple reasons: I get the error below when running the test code, and The output does not go to the console unless I go into teleop mode.

Why is the output delayed and why did this error occur? Any easier ways to output data? File I/O does not work. I have tried using cout and printf, and both have this problem. Usually cout works better

Code:

double integral(double angle, double x)

{

        double result = 0;

        int n = 1;

        result += gyros[0];

        if(x > 0.1)

        {

                for(double i = 1; i <= x * 10; i += 1)

                {

                        result += 2*gyros[i];

                        n++;

                }

        }

        result += angle;

        result *= x/(2*n);

        std::cout << result << '\n';

        return result;

}



void Test() override

{

        for(int x = 0; x < 10000; x++)

        {

                double angle = gyro->GetAngle();

                myRobot->Drive(0.15, -Kp*angle );

                gyros.push_back(angle);

                std::cout << x << ' ' << Kp*integral(angle, x) << ',';

                printf("%d %e,", x, Ki*integral(angle, x));

                Wait(0.01);

        }

        myRobot->SetLeftRightMotorOutputs(0.0, 0.0);
