Minecraft crashing on startup

Every time I try to start up the game, the launcher loads up, a Minecraft window pops up for a split second, then it crashes and takes me back to the launcher with an error reading "An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience" (provided a picture down below). I'm not using forge or anything, I'm just trying to run the game regularly. I also provided a text document that I think is the crash log. I'm not sure if that's it or not though because whenever this happens it doesn't show up in my crash-reports folder. Hope someone can help me out, thanks
