Android Studio – Observer is called twice at the same time in Kotlin

When the button is clicked, data is received from the API, after which the Observer is fired, however, even with removeObservers, it is called twice.
Without removeObservers it triggers more than 2 times.

MainActivity

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

    setContent {
        TestApiAppTheme {
            Surface() {
                TextInfo()
            }
        }
    }
}

@Preview
@Composable
fun TextInfo() {

    val viewModel = ViewModelProvider(this).get(MainViewModel::class.java)

    var txt = remember {
        mutableStateOf(0)
    }

    viewModel.serverInfoResponse.removeObservers(this)
    viewModel.serverInfoResponse.observe(this) {
        txt.value = it.players
        Toast.makeText(this, "${it.players} -", Toast.LENGTH_SHORT).show()
    }

    Column() {
        Text(
            text = txt.value.toString(),
        )

        Button(onClick = {
            viewModel.getServerInfo()
            visible = true
        }) {
            Text("Update")
        }
    }
}}

ViewModel

var serverInfoResponse = MutableLiveData<ServerInfo>()

fun getServerInfo() {
    viewModelScope.launch {
        val apiService = ApiService.getInstance()

        val info = apiService.getInfo()
        serverInfoResponse.value = info
    }
}
