Warzone issue please help!

im trying to get call of duty warzone and when i install it says updating and then the mb percent go up until about 18mb for a couple seconds then it freezes for like 20-40 secs. After its done freezing it says initializing for 1 sec then applying updates for a sec then it starts back up at the same % but the mb restarts back to 4mb then goes up to about 18-20 and this happens over and over
