Chrome Extension restarts on its own when service worker is not open

Question

Whenever I have the service worker opened, my chrome extension seems to work perfectly but whenever I do not have it opened, seconds later the chrome extension just restarts on its own without any saved data. I have tried using Chrome.Storage API but I still have the same issue. I'm not sure if I coded it incorrectly or if I am just not implementing it correctly in the rest of the background script. Any help is appreciated. Thank you

background.js

let currentTime = startingMins * 60;
let counter;
let ifTimerOver = true;

  if (request.cmd === "STOP_TIMER") {
    stopTimer();
    sendResponse({ time: currentTime, timerOver: ifTimerOver });
    resetTime();
    console.log("background.js - stop timer");
  } else if (request.cmd === "START_TIMER") {
    currentTime = request.when;
    startingMins = request.strarting;
    storeCurrrentTime();
    storeStartingMins();
    startTimer();
    console.log("background.js - timer started");
  } else if (request.cmd === "GET_TIME") {
    sendResponse({
      time: currentTime,
      timerOver: ifTimerOver,
      startedMinutes: startingMins,
    });
    console.log("background.js - sending current time");
  } else if (request.cmd === "RESET_TIME") {
    clearInterval(counter);
    resetTime();
  } else if (request.cmd === "STORE_URL") {
    let tempURL = request.link;
    storeURL(tempURL);
  } else if (request.cmd === "GET_DATA") {
    sendResponse({ link: blockedDomains });
  } else if (request.cmd === "CLEAR_URLs") {
    clearAllURLs();
  } else if (request.cmd === "DELETE_URL") {
    let del = request.link;
    deleteURL(del);
  } else if (request.cmd === "CONTENT_SCRIPT_INIT") {
    // is timer running
    sendResponse({
      time: currentTime,
      isRunning: !ifTimerOver,
    });
  }
  return true;
