Crash found on Camera2Source.stop

[adhithyagnair]

I'm getting a inconsistent crash on camera2Source when scanning barcode.
It is quite too common in Honor 9 lite (Android : N )device and I'm also getting on other devices, but it is hard to reproduce.

This is the crash log I have got from firebase
