So my game keeps acting weird, I need a diagnosis

So while playing the game, usually in Warzone, rarely in Arena, the textures of the map will at random times turn black, the game will freeze, and I will be kicked to the home screen. It happens very often, and I don’t know what the cause should be. I may link a video of it happening soon, but my question is how should I go about fixing these random crashes? What could be causing the textures to randomly go black and the game to crash?

EDIT: Here’s a link to a short video of my problem. Hope you guys can help me out. https://www.youtube.com/watch?v=YlvbUMLIlU4&feature=youtu.be
