The Chorus RF Laptimer v 0.75 application crashes when trying to reenter it

[ammarraisafti]

Expected behavior

After opening the Connect via Bluetooth feature, then switch to landscape display mode. the ability to switch to landscape view mode should be possible. And once the user exits the app. the ability to enter into the application too should be possible.

Actual behavior

After unlocking the Connect via Bluetooth feature, then switching to landscape display mode, I redirected to the main page of the app. Next I minimize the app, then log back into the app, suddenly the application crashes and stops.

How to reproduce

1. Install and open the app.

2. Click the top right shortcut, then select and open the Connect via Bluetooth feature.

3. Next you have to switch to landscape display mode, then you will find the problem as I have experienced. Redirected to app main page.

4. Next you have to minimize the application, then log back into the application. Then you will find the problem as I have experienced. The application suddenly crashes and stops.
