My app is a fork of open source FileX App, which is also hosted on the Playstore and working fine in the release mode for android App.
github link of my project

In the release mode it is not fetching Recent Files. Image, video, Audio etc are also not working in release mode but in debug mode and profile everything is working nicely.

I’ii request you to give it a try.

Tried in Profile mode and release mode.
Expecting to also work in the release mode too
