How can i return a list in GlobalScope (with sth like remember{}) in Jetpack Compose

Question

I can return a String in GlobalScope by "remember { mutableStateOf("") }" and i try to return a list by sth like "remember { mutableStateListOf() }" and log.d to print it then the app will crush.

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        var n = 1
        setContent {
            WannaJsoupTheme {
                    var returnStr = remember { mutableStateOf("") }
                    var returnList = remember { mutableStateListOf<String>() }
                    mutableStateListOf<String>()

                    GlobalScope.launch(Dispatchers.IO) {
                        if (n == 1) {
                            val doc = Jsoup.connect(someUrl).get()
                            val box = doc.select("span[class=img]")

                            box.forEach {
                                returnList.add(it.select("img").attr("src"))
                            }
                            n++
                        }  
  // now i only can use  returnStr.value = returnList.joinToString ("#") 
   // and split it later...
  
                    }
                  Log.d("TAG", returnList[0])
           }
        }
    }
}
