Update your deps with npm update then rename your username to something else and try again

[overtimepog]

even after update

const mineflayer = require('mineflayer')
const { mineflayer: mineflayerViewer } = require('prismarine-viewer')

const bot = mineflayer.createBot({
  host: 'play.callmecarson.live', // minecraft server ip

  // password: '12345678'      // set if you want to use password-based auth (may be unreliable). If specified, the `username` must be an email

Did you do this part?

then rename your username to something else and try again

[overtimepog]

const mineflayer = require('mineflayer')
const { mineflayer: mineflayerViewer } = require('prismarine-viewer')

const bot = mineflayer.createBot({

I fixed it, for anybody who comes across this problem later this is my code

const mineflayer = require('mineflayer');
const { mineflayer: mineflayerViewer } = require('prismarine-viewer');
const pathfinder = require('mineflayer-pathfinder').pathfinder;
const Movements = require('mineflayer-pathfinder').Movements;

  host: 'play.callmecarson.live',
  auth: 'microsoft',
  version: '1.20.2',
});

console.log("Bot is starting...");

bot.on('login', () => {
  console.log("Bot has logged in!");
});

  bot._client.write('resource_pack_receive', { hash: "Resourcepack", result: 3 });
  bot._client.write('resource_pack_receive', { hash: "Resourcepack", result: 0 });
});

bot.on('message', (jsonMsg) => {
  console.log(jsonMsg);
});

bot.loadPlugin(pathfinder);

let followingPlayer = null;
let followGoal = null;
let spleefMode = false;

function updateFollowGoal() {
  if (followingPlayer) {
    const player = bot.players[followingPlayer];
    if (player && player.entity) {
      const mcData = require('minecraft-data')(bot.version);
      const movements = new Movements(bot, mcData);
      movements.scafoldingBlocks = [];
      bot.pathfinder.setMovements(movements);

      const goal = new GoalNear(player.entity.position.x, player.entity.position.y, player.entity.position.z, 1);
      followGoal = goal;
      bot.pathfinder.setGoal(goal, true);
    } else {
      followingPlayer = null;
      followGoal = null;
      bot.pathfinder.setGoal(null);
      bot.chat("Player not found. Stopping following.");
    }
  }
}

function spleefBehavior() {
  if (!spleefMode) return;

  const player = bot.players[followingPlayer];
  if (player && player.entity) {
    const blockBelow = bot.blockAt(player.entity.position.offset(0, -1, 0));
    if (blockBelow && blockBelow.name === 'snow_block') {
      bot.dig(blockBelow, true);
    }
  }
}

    bot.pathfinder.setGoal(null);
    bot.chat("Stopped following.");
  } else if (message === "spleef mode" && username === "overtimepog") {

Actually, none of that should be relevant, your issue is caused before the client is able to join the server at all. This means you need to 1. update your dependencies and 2. ensure that it's not caused by an invalid cached credentials by changing your username to force a re-sign in.
