Launching app on android fails

I encountered this weird problem which you can’t launch the game on the phone(Android),

I played my game on mobile preview, and it worked perfectly.

Then I packaged it, played on the up to date samsung and LG phone that can run almost any game.
(Samsung Galaxy Fan Edition, V30+)

After all, I keep on seeing the default menu of the phone.

What problems can cause this issue?

One thing I suspect is that I included a blank map as a start map for the game.

This was intended to display main menu without any lag, then when you actually press “play” button,

The game will load the primary map, which is quite heavy.

Does this empty map can cause the problem?

I excluded this empty map and tried again, but still didn’t work on the phone.

I’m having the same problem.
