Pressing on mobile back button when editing creates an unexpected error on android

[Abhisflyingsoon]

Test steps:
take picture → crop image → press "+" - Button -> camera opens → press hardware back button → press check button -> unexpected error occurs = Error: error - unable to crop image: cv::Exception: OpenCV(4.1.0) /build/master_pack-android/opencv/modules/imgproc/src/color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cvtColor'

Tested it on a few android devices and simulator. Error occurs everytime.

+1 getting this as well.

Exactly as stated above, hitting back then hitting the check button results in that error.

It still occurs if you hit the + again and take another pic before hitting the check button.
