when I launch Minecraft, it will work for about five seconds and then crash.

When I launch Minecraft, I'll start playing and then it crashes with a black screen.

Usually I would start minecraft and play and there would be no problems whatsoever. What actually happened was that when I launched Minecraft, it would crash and java would give me a warning saying something like, "Using incremental CMS is deprecated and will likely be removed in a future release." It also says that it crashed outside of java and the error happened in native code.
This is what was on the launcher log after minecraft crashed:
