同时更新/使用MutableStateFlow时出现ConcurrentModificationException，如何防止？
代码片段：

class SearchViewModel() : ViewModel() {

val searchState = MutableStateFlow(SearchState())

private fun getItems() = viewModelScope.launch {
    ....
    object : Callback<Results> {
        override fun publish(items: Results): Boolean {

            searchState.value = searchState.value.copy(   // <--- ConcurrentModificationException at emit() function
                currentItems = items
            )
        }
    }
}

@Composable
fun ScreenContent(viewModel: SearchViewModel) {

    val state by viewModel.searchState.collectAsState()

    Column(
        modifier = Modifier.fillMaxWidth()
    ) {
        // \/ ConcurrentModificationException here sometimes as well
        state.currentItems.forEachIndexed { index, searchRowItemData ->
            SearchRowItem(searchRowItemData, index == state.currentItems.lastIndex) {
                onItemClicked(searchRowItemData)
            }
        }
    }
}

我想问题是我同时更新和迭代searchState属性，但是如何解决呢？
