Apex legend failed to launch

So I am not playing Apex for a while 2 days ago I still can be able to launch the game but I think it's getting strange since I wanna play control and no one is in the lobby. It said waiting for players but there's only one and I believe is me. I closed the game and the next day there is an update so I updated the game. One thing here I don't know why it said it requires 66gb and I only got 3gb left in my D drive. I know how to solve this stupid thing and I uninstalled the game and reinstall it, it's in my D drive now. Is it kind of a bug or something? Anyway, so I was so excited to launch the game it said the game requires permission. Well, I clicked ok and it turns into another bug/error report that said 'An error on our end caused your launch to fail. try again a little later.' I already ensure that I gave the permissions to the anti-cheat launcher and Apex legends, there's a tick in the box about giving admin permission. Till now, I had ever tried to uninstall the game 3 times and reinstalled EA app 3 times it still doesn't work. Please help, I tried many ways to slove the problems but it just doesn't work. btw, I am not a English person so if there's any grammar mistakes or you don't understand please tell me lol. Again, I will be very appreciative if someone could help me with this problem, EA is just a piece of * to leave the problems to the player slove it themselves.
