I get an error saying can't load dependency assets music/null.mp3

Error:com.badlogic.gdx.utils.GdxRuntimeExeption

Running on xiaomi redmi 4 on with latest patch and on latest version of the game. Fresh downloaded and first time install. It says there is a .txt somewhere in game files , but can't find them.

Seems like Android had just given up and died. No music whatsoever was recognized from the phone. After a couple of phone restarts it decided to work.
