Minecraft : La dernière version de Forge 1.12.2 ne se lance pas

Bonjour,

Depuis peu j'essaie de lancer Forge en 1.12.2 dans sa version 14.23.5.2854. Cette dernière refuse de se lancer et le jeu crashe avant que la fenêtre s'ouvre. Cependant, elle m'est nécessaire afin de lancer certains mods. Toutes les autres versions de Minecraft fonctionnent, j'ai même essayé de ne mettre qu'un mod.

J'ai déjà mis mes pilotes de carte graphique à jour et réinstallé le jeu. Je ne comprend pas la cause de ce crash. Voici la log que le launcher me présente lorsque celui-ci crash :
