Kotlin app crashes after Launch succeeded with no error message

I'm making a new Empty Compose Activity from android studio and when I run the app it says Launch succeeded but the app crashes immediately after the android logo appears without any error messages.
Here's my gradle files:

I tried running it on emulator and real device but both gave the same problem.
At first launch I got a composer error where the version was 1.1.0-beta01 so I changed it to 1.2.0-alpha07 and it worked.

java.lang.NoSuchMethodError: No static method for Jetpack Composable

I'm creating an Android Library for basic dialogs. Right now, all I have is a basic-dialogs module along with the app module. I'm calling a composable in the basic-dialogs module from the Activity in the app module, and I keep getting the exception error message below about a No static method when I try to run the app. What could be wrong with the code?

Cleaning build, then rebuilding fixed the issue for me.

ComposeView is very slow when opening the fragment for the first time

I added compose to an existing project.
I rewrote a fragment ui with compose, and when I'm starting the
fragment it takes a long time to start.
Adding a fragment from another fragment:
val fragment = FragmentWithComposeUi()
requireActivity().addFragment(fragment, R.id.fragment_container, "FragmentWithComposeUi")
addFragment() function to add the fragment.
fun FragmentActivity.addFragment(fragment: Fragment, container: Int, tag:String) {
val currentFragment = supportFragmentManager.findFragmentByTag(tag)
if (currentFragment == null) {
supportFragmentManager.beginTransaction()
.setReorderingAllowed(true)
.add(container, fragment, tag)
.addToBackStack(tag)
.commit()
}
}
FragmentWithComposeUi class :
class FragmentWithComposeUi: Fragment() {
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View {
return ComposeView(requireContext()).apply{
setContent {
//some ui
}
}
}
build.gradle
I tried using the new compose version 1.3.0-alpha01 either, it doesn't help.

ext {
compose_version = '1.1.1'
compose_compiler_version = '1.2.0'

I can't access rememberCoroutineScope() and i updated android studio to last version , so how i can solve this problem,

i solved this problem jetback compose after update from beta , There are no kotlinx.coroutines so if you want kotlinx.coroutines and use :
import androidx.compose.runtime.rememberCoroutineScope
and
rememberCoroutineScope()
just Add kotlinx-coroutines-android module as a dependency when using kotlinx.coroutines on Android:
implementation("org.jetbrains.kotlinx:kotlinx-coroutines-android:1.6.0")
