Can’t access game modes on Battlefront (2015) PS4

I have the game updated to the newest version and tried deleting and redownload the game, but when I open up the game, I only get one option: “Embrace the dark side of the force. Wipe out as many rebel scum as you can while battlefront installs. X to start mission”, which is only single player and I am invincible (which is not fun or challenging). I want to play with my brother like we did many years ago but the game won’t let us, pls help or tell me if you have the same problem.
