Battlefront will not load to a menu screen only a battle involving Darth Vader

we tried at least 10 times....It literally does not give him a choice, once you load the disc plus the updates it throws him right into a never ending battle and you never get the EA screen nor the main menu....The only thing you see is the battlefont still screen, then switches to a still of Darth Vader and says play this while your game is finished loading, like I said we exit out of it and look at the progress bar for the install and it's 100 percent complete... Let me throw this out there....Is it possible that this is happening because we have 2 playstation 4's??? I bought a new one for myself with the battlefront game, installed it and played it no problem. I bought a second copy for my son, totally different disc. I am wonderING if because this caosmaster EA account is linked through the same email that my new ps4 was set up under, if the game is crossing information between both ps4's, or if there is an actually problem with the game itself I purchesed for him??? It's very strange
