Occasionally, I have this glitch where I boot up Minecraft, but the application is silent. I don't know why, or how it happened, but the only way to fix it is to close Minecraft AND the launcher, and then reboot. I don't know any more.

Please attach the complete output of the "Game Output (Your Minecraft name) " which can be found on the fourth tab of the launcher to this ticket.
If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".
