Component used: Fragment

Version used:

• activity = "1.9.2"
• fragment = "1.8.3"
• transition = "1.5.1"

Devices/Android versions reproduced on:

• Android 14 / Pixel 8

(this was already marked as fixed in https://issuetracker.google.com/issues/338624457, but the crash still exists in the latest library versions)

You can find a minimal sample repo here: https://github.com/kroegerama/android-fragment-crash-sample

Setup in fragment:

[...]
import androidx.transition.Fade
[...]

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    enterTransition = Fade().setDuration(600)
    exitTransition = Fade().setDuration(600)
}

I'm getting this crash, when I navigate forward multiple times (navigate(FragFooDirections.actionFooBar())) and then repeatedly in quick succession use the back gesture or back button (popBackStack()).
