### Steps to reproduce

In the app Nextcloud:
Before it happens I open the video format file in a deep folder, (5 folders)
After that, I quit with the back button and get directed to the media tab
And then I click a random file (but it's still a video format),
and I quit (got directed to the media tab).
After that, I wanna go back to the menu by pressing the back button.
But it's crashed

### Expected behaviour

It must be directed to the dashboard (Menu) before the crash happened.
