Hola!

Soy nuevo en esta comunidad porque desde hace tiempo me ocurre un problema que no me permite jugar.
Cuando salio la actualización del Launcher lo descargue, y desde ese momento este error me aparece siempre.
y he instalado y desinstalado Minecraft y cambiado la versión de Java "80 veces" y nada.

Ayudadme por favor.

Os dejo a qui los datos del error:
