Problème pour lancer Minecraft Forge Depuis une installation

Bonjour !

J'ai un problème depuis hier que j'ai essayé de résoudre avec d'autre méthode que j'ai trouvé sur ce forum mais aucuns résultats.

Le contexte :

Avant je jouais en Minecraft ( Forge ) 1.8 sans problème , mods actifs etc etc ...
Étant donné que je suis un joueur minecraft fan de PvP , je commence l'installation d'un minecraft forge 1.7.10 , avec des mods blablabla ... Tout marche nickel en 1.7.

Suite a ça , j’arrête de pvp , et je veux faire des SKyWars avec un ami/ Je lance donc mon minecraft en 1.8(Forge) mais ce dernier ne se lance pas !

Ce que j'ai fait pour lancer minecraft :

Ouvrir le launcher , sélectionner la version 1.8(Forge) et cliquer sur PLAY ...
Le launcher se ferme et ... et bah rien , le jeu ne s'ouvre pas : /

Ce que j'ai déjà fait :

Supprimer et réinstaller mon Forge
Retirer tout les mods et essayer de relancer le jeu ( sans resultats)


J'ose pas trop toucher au java de peur de tout planter :§

Je vous colle ici les logs que j'ai obtenu ( Game OutPut) :
