Arena and Character selection bugged

When ever I launch apex l, it gives me the loading screen for like 2 minutes and then says it couldn’t connect to the server, I try again and the 2nd time it works. Then I change my mode from trios to arena, all of a sudden the game starts to freeze up and break. It kicks me out of the game to the click to start page. I then click and the game loads for a while and I’m back in the lobby in arena mode. When I ready up, I get the loading screen the entire time and I am not able to pick my character, sometimes I’m not able to even buy.
