Launcher crash

After I press the start button the launcher closes and it reopens with this message:

[16:39:57] [main/INFO]: Setting user: VapeInjected
[16:39:57] [main/INFO]: (Session ID is <censored>)
Completely ignored arguments: [--nativeLauncherVersion, 1148]
[16:39:57] [Client thread/INFO]: LWJGL Version: 2.9.1
I already tried to reinstall minecraft but it did not help.
