setInterval and clearInterval for rock paper scissors

Question

I am new to JS and trying to finish Rock, Paper, Scissors, Lizard, Spock game. The only thing left to fix is shuffle emoji speed if I press 'Next round' button more than once.

I am struggling with clearing Interval . If click more than once on 'next round' button the interval speed increases and can't clear it even if clicking on emojis. Any suggestions?

I tried to use a for loop to clear interval each time 'next round' button is clicked more than once but just more confused how to solve it.

// ----------------------GAME----------------------
// Add active class to the current button (highlight it)
var header = document.getElementById("player-choice-container");
var btns = header.getElementsByClassName("emoji");
for (var i = 0; i < btns.length; i++) {
  btns[i].addEventListener("click", function() {
    var current = document.getElementsByClassName("active");
    current[0].className = current[0].className.replace(" active", "");
    this.className += " active";
  });
}

// Counting score 
let playerScore = 0;
let computerScore = 0;
let moves = 0;

let userChoice = "";
let computerChoice = "";

let emojis = ["✂️ ", "", "", "", ""];
let currentEmojiNumber = 0;

let shuffleIntervalID;

let userChoiceContainer = document.querySelector("#player-choice-container");
let emojiShuffleElement = document.querySelector("#emoji-shuffle");


userChoiceContainer.addEventListener("click", handlePlayerChoice);

// Function to get player choice
function handlePlayerChoice(event) {
  if (!event.target.classList.contains("emoji") || moves >= 10) return;
  userChoice = event.target.textContent;
  clearInterval(shuffleIntervalID);
  moves++;
  document.querySelector('.movesleft').innerText = `Moves Left: ${10 - moves}`;
  determineWinner();
  if (moves == 10) {
    gameOver();
  } else {
    shuffleEmojis();
  }
  determineWinner();
}

// Function to generate computer and user choice
let nextRound = document.getElementById('next-round');
nextRound.addEventListener('click', nextRoundBtn);

// Function to reset user and computer choice and pick choice again
function nextRoundBtn() {
  shuffleIntervalID = setInterval(shuffleEmojis, 150);
}

function playerEmojis() {
  playAgainEmoji = getElementById('player-choice-container');
  userChoiceContainer.textContent = playAgainEmoji;
}

// Function to return a random emoji from the dictionary and  genenerate computer choice.
function shuffleEmojis() {
  computerChoice = emojis[currentEmojiNumber];
  emojiShuffleElement.textContent = computerChoice;

  if (currentEmojiNumber < emojis.length - 1) {
    currentEmojiNumber++;
  } else {
    currentEmojiNumber = 0;
  }
}
