Html – Rock Paper Scissor Game…showing only computer as winner for every condition. what mistake i am making

I am trying to build rock paper scissor game. In this for every condition it is showing computer as winner and only the computer score is increasing. In playRound function the conditions are correct i am not able to rectify the problem here. Plz help in finding my mistake.

const choices = ["rock", "paper", "scissors"];
let computerScore = 0;
let playerScore = 0;
var computer;

function computerChoice() {
    const computerId = document.getElementById('computerid');
    computer = choices[Math.floor(Math.random() * choices.length)];
    computerId.innerHTML = computer;
    console.log(computer);
    return computer;
}

function playRound(computerSel, playerSel) {
    return (computerSel === playerSel) ? "It's a Tie" :
        (computerSel === "rock" && playerSel === "scissors") ||
        (computerSel === "paper" && playerSel === "rock") ||
        (computerSel === "scissors" && playerSel === "paper") ? "Computer" : "Player";
    }

var playerSelection;
var computerSelection;
function playGame() {
    const buttons = document.querySelectorAll('button');
    buttons.forEach(btn => {
        btn.addEventListener('click', (e) => {
             playerSelection = e.target.textContent;
             console.log(playerSelection);
            const playerId = document.getElementById('playerid');
            playerId.innerHTML = playerSelection;
             computerSelection = computerChoice();
            const result = playRound(computerSelection, playerSelection);
            console.log(result);
            updateScore(result);
            
        });
    });
}

function updateScore(result) {
    const playerscore = document.getElementById('playerscore');
    const computerscore = document.getElementById('computerscore');
   
    if (result === "Player") {
        playerScore++;
    } else if (result === "Computer") {
        computerScore++;
    }
    playerscore.innerText = playerScore;
    computerscore.innerText = computerScore;
    if (playerScore === 5 || computerScore === 5) {
        endGame();
    }
}

function endGame() {
    const winner = (playerScore > computerScore) ? "Player" : "Computer";
    console.log(`The winner is ${winner}`);
}

playGame();
