[Camera2Basic] Application not responsive after taking X pictures

Device and System: Multiple, multiple emulator configurations, multiple hardware devices.
No real error in logcat.

Steps:
Remove `navController.navigate...` part from [here](https://github.com/android/camera-samples/blob/6cbd2cc5a5318029f889fb46b4509c869b454856/Camera2Basic/app/src/main/java/com/example/android/camera2/basic/fragments/CameraFragment.kt#L248).

I want to take multiple pictures, so, just spam the capture button, it happened after 50 as well as 3 pictures on a real device where the bug seems to be popping more often.

Start in Camera2Basic/app/src/main/java/com/example/android/camera2/basic/fragments/CameraFragment.kt around line 248, then reproduce the issue by rapidly taking multiple pictures on an emulator or device. Trace the navigation triggered after capture and compare behavior with that navigation call removed; done means repeated captures no longer make the application unresponsive.
