I was kicked at the start of a competitive game, lost 50 sr, and received this error code: 447AB25D-77DA-488A-84A5-95037CCBBE24. What does this mean and is there anything I can do to prevent this from occurring?
Hello DTrix 
Sorry to hear you’re running into game crashes, and while we’re unable to modify competitive rankings, we can certainly look into issues leading to those crashes.
From the error code you posted, I can see your video driver and operating system are due for updates (the video driver being quite a bit further behind than the OS, but hey, let’s get 'em both).
Beyond this, we’ll want to make sure no other programs are interfering with the game’s processes in unforeseen ways. The following steps will guide you through shutting down non-Microsoft programs that boot up automatically:
Closing Background Applications
Best of luck in your adventures
