Lately we are seeing a crash in our QT based SoundTouch Application.

Here's the crash exception:

Steps to reproduce:
1) Download MacOS SoundTouch app from https://downloads.bose.com/ced/soundtouch/soundtouch_controller_app/index.html
2) Install the SoundTouch App
3) Launch the App

Actual Result:
Immediately crashes as soon as I open the App

Expected Result:
To work as expected with out crashing.

Notes:
Only Japan customers are affected by this issue and the issue is happening irrespective of their MacOS Language.
We also have another Campanion app built with QT5.7.0 and observed the same crash there too.
Also we currently have no plans in updating QT library. It would be good if you could suggest a fix in QT5.7.
