Why is the code after my for loop not running?

<script>
    
    //references the submit button, runs if it is clicked
    const sub = document.getElementById("sub");
    sub.addEventListener("click", (e) => {
    e.preventDefault();
    
    //references every input number
    var in1 = document.getElementById("in1").value;
    var in2 = document.getElementById("in2").value;
    var in3 = document.getElementById("in3").value;
    var in4 = document.getElementById("in4").value;
    var in5 = document.getElementById("in5").value;
    
    //creates an array and puts all of the inputted values into it
    const inputs = new Array();
    inputs.push(in1, in2, in3, in4, in5);
    
    //references all of the circles
    var num1 = document.getElementById("num1");
    var num2 = document.getElementById("num2");
    var num3 = document.getElementById("num3");
    var num4 = document.getElementById("num4");
    var num5 = document.getElementById("num5");
    
    //creates an array and stores all of the references to the circles in it
    var circles = new Array();
    circles.push(num1, num2, num3, num4, num5);
    
    //creates an array for the generated numbers
    var generated = new Array();
    
    for(i = 0; i < 6; i++){
        //fills the array with 5 random numbers
        let gen = Math.round(Math.random() * 38);
        generated.push(gen);
        //changes the numbers in the circles to the random numbers
        circles[i].innerHTML = generated[i];
    
    }
    
    alert("test");//this doesn't pop up
    
    });

All of my code up to this point works perfectly, and the numbers are correctly added to the circles, but then anything I write after the for loop does not run, and I cannot figure out why. If the alert is anywhere else in the code above the for loop, it pops up with no issues.
Any help is greatly appreciated.

I tried to make an alert pop up to check if anything was running after the for loop, and it did not pop up.
