MutableStateFlow does not emitting value changes

Question

Case is,I'm scanning hardware with NFC and getting texts from it,it has some steps to receive texts.for example:

step 1 - starting scan, step 2 - scan in progress, step 3 - scan is almost finished, step 4 - scan is finished.

Problem is when I send messages while scanning hardware,I receive all of them,checked it with logs and text is appearing in Logcat,but when I'm setting new value to MutableStateFlow inside ViewModel,it only reacts on start scan and finishing scan,I've also used debugger to see if value is changing or not,value of MutableStateFlow object is changing but it's not emitting new value to composable.In composable I'am using collectAsStateWithLifecycle().

this is view model where I receive messages as String

 override fun sessionMessage(message: String) {

        if (message.contains("Error")) {
            sessionError = message
        }
        else {
            Timber.tag("TEXTSHOWNVIEMODEL").d("$message")
            textShown.value = message
            Timber.tag("TEXTSHOWNVIEMODEL").d("${textShown.value}")
        }
    }

as you can see,I'm logging MutableStateFlow object value , it's changing when I'm setting new value but it does not emits new value to composable.This is my MutableStateFlow object

var textShown = MutableStateFlow<String>("Press upon NFC tag to continue")

and this is where I should receive info about changes

val text = viewModel.textShown.collectAsStateWithLifecycle()

this is composable Text where I'm assigning this new value but it's not even receiving above

Text(
            text = text.value ?: "",
            style = MaterialTheme.typography.h6,
            modifier = Modifier.align(Alignment.CenterHorizontally)
        )
