android livedata fragment memory-leak Kotlin

I'm wondering if anyone has experience with I'm trying to figure out I'm encountering a memory leak issue in my Android 14 app related to LiveData observers tied to my Fragment lifecycle. I've followed the standard practice of observing LiveData in `onViewCreated`, but it seems that the observer is still holding a reference to my Fragment, even after it gets destroyed. This leads to a situation where I see the `LeakCanary` report pointing to the Fragment as leaked when navigating away from the screen. Here's a simplified version of the code I implemented: ```kotlin class MyFragment : Fragment() { private lateinit var myViewModel: MyViewModel override fun onViewCreated(view: View, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) myViewModel = ViewModelProvider(this).get(MyViewModel::class.java) myViewModel.myLiveData.observe(viewLifecycleOwner, Observer { data -> // Update UI with data updateUI(data) }) } } ``` I’m using `viewLifecycleOwner` as I thought this would automatically handle the lifecycle correctly. However, I still sometimes see the Fragment being retained longer than expected. I've also checked for any other long-lived references to the Fragment that could cause this but didn’t find any. Additionally, I tried using `removeObservers(viewLifecycleOwner)` in the `onDestroyView` method, but it doesn’t seem to help. The memory leak persists. I’ve also tried invalidating my LiveData instance and recreating it in `onCreateView`, but that didn’t work either. Could this be an issue specific to the Android 14 version, or am I missing something fundamental with LiveData’s binding to the Fragment lifecycle? Any insights would be greatly appreciated! Thanks in advance! Am I missing something obvious?
