Component used: androidx.slidingpanelayout:slidingpanelayout
Version used: 1.2.0
Devices/Android versions reproduced on: Pixel 6 Pro, Samsung S10, etc...

Problem is sometimes an ANR is produced, see tombstone attached.

To reproduce:
Using a custom onBackPressCallback:
val onBackPressedCallback = object : OnBackPressedCallback(true) {
        override fun handleOnBackPressed() {
            lifecycleScope.launch {
                withContext(Dispatchers.Main) {
                    viewModel.closeSlidingPaneEvent.value = Event(true)
                }
            }
        }
    }

In my fragment I observe the event:
viewModel.closeSlidingPaneEvent.observe(
            viewLifecycleOwner
        ) {
            it.consume {
                binding.slidingPane.closePane()
            }
        }

Event class is as such:
open class Event<out T>(private val content: T) {
    private val handled = AtomicBoolean(false)

    fun consume(handleContent: (T) -> Unit) {
        if (!handled.get()) {
            handled.set(true)
            handleContent(content)
        }
    }
}
