Impossible to say without more information.
-Are you using any non official plugins?
-Does the compile log in XDK look ok?
-Do you use minify on export from construct2?
-Does other games work for you on export on your device(try a simple demo project and see if that works out of the box on your device)
-Do you see any error in Chrome in its Console? (press F12)
There are a thousand things that can go wrong....start simple and test often!
Pluggins no more that construct have by default

in the game run until the main screen but in the buttons any of then the game close
I test the game on Chrome and work fine
