Github issues under this project are only for sample-related issues. If you have modified the sample code in any way, then this is probably not the appropriate place to report a bug.
Include the specific sample where you found the issue, in addition to device model and specific Android build number -- which can be found under Settings > About phone.
Include error logs from logcat, if there are any.
If you can, also attach a bug report-- but please keep in mind that personal information can sometimes be found in those, so double check before attaching.

I think the issue is the call to property fragmentCameraBinding via overlay.postDelayed. The property is defined as _fragmentCameraBinding!!, but in the delayed call sometimes the value is null -- probably due to clear in onDestroyView. I think a better implementation is using a lateinit field and no property:
private lateinit var fragmentCameraBinding: FragmentCameraBinding
I think the sweet spot for lateinit is exactly this scenario: a variable that is basically immutable but initialized after ctor.
