该问题可能是由于网络连接问题导致的。可以尝试使用AWS IVS SDK提供的重连策略来解决。以下是示例代码：

import {
  PlayerState,
  PlayerEventType,
  PlayerStateIdle,
  PlayerStateLoading,
  PlayerStateReady,
  PlayerStateEnded,
  PlayerStateError,
  Html5VideoStreamer,
  IvsVideoJSAdapter as IvsPlayer,
  IvsConfig,
} from "amazon-ivs-player";

let video = document.getElementById("myPlayer");
let options = {
  logConfig: {
    level: "DEBUG",
    logger: console,
  },
  bufferingGoal: 20,
  rebufferToLive: true,
  enableLowLatency: false,
};
let config = IvsConfig.newInstance(options);
let player = new IvsPlayer(config);

player.attachHTMLVideoElement(video);

player.addEventListener(PlayerState.PLAYING, () => {
  console.log("IVS player is playing");
});

player.addEventListener(PlayerState.IDLE, () => {
  console.log("IVS player is idle");
});

player.addEventListener(PlayerState.LOADING, () => {
  console.log("IVS player is loading");
});

player.addEventListener(PlayerState.ERROR, () => {
  console.log("IVS player encountered an error");
  // 尝试重新连接
  player.load("CHANNEL_ARN");
});

在此示例代码中，当播放器遇到错误时，会触发错误事件并尝试重新连接。通过这种方式，可以解决大多数由于网络问题导致的播放器卡顿问题。
