Expected behavior

Supposedly, when the user rotates rotation from portrait mode to landscape mode the "Search" feature does not crashes.

Actual behavior

When accessing the "Search" feature in portrait mode, the feature works normally. However, when I rotate the rotation to landscape mode the application suddenly crashes and exits without a command.

How to reproduce

• Install and open the app
• Run the app and click on the "Search" icon.
• Next step, rotate to landscape mode, then the app will crash.
