Expected behavior

Supposedly, when I exit the application in the middle of the scanning process, and try to reopen the application, the application will not experience an error.

Actual behavior

Initially, I tried to select the folder to add music. Then I go to the "Music Player" and wait for the scanning process. And when the scanning process takes place I accidentally exit the app, but after trying to reopen the app, the app suddenly crashes or bounces.

How to reproduce

1. Install and open the app

2. Then go to menu "Folder" and do select folder
   

3. Next, go to the "Music Player" page. And in the middle of the scanning process takes place, then exit the application.

4. Next, reopen the app. Then you will see the application will crash and bounce out.
