Constant crashes/Bugsplat during games on Mac

My client continues to crash during or even before games. Sometimes the game will crash multiple times while in a game. I have a 2014 MacBook Pro. I never had any issues until the Azir patch. My client wouldn't even update until a month after the Azir patch and now it is constantly crashing, even after 4.20. I have turned the graphics settings down as well and the game still crashes. It even crashed during a Custom AI game.

What do I do?
