how to fix apex legend glitch

Hi,

I currently have a problem when playing Apex Legend, when I'm at the lobby waiting for a game my legends head can't be seen it's all black, when I view my legends for example Wraith she's bald even I dont have that kind of skin yet and Blood Hounds face is half black. When I'm still sky diving from the jet I can't see the mountains and other players diving I only see their color trails. And when I'm on the ground already I can see through walls and I can't see the stairs and buildings. Please help, I really want to play the game again normally. 

Thanks,
