Mon Minecraft 1.12.1 ne répond pas :***((

Bonjour, j'ai installé un pack de texture (BDcraft) sur le site officiel et l'ai mis dans les dossiers .minecraft, j'ai lancé le jeu et séléctionné BDCraft mais quand je l'ai appliqué, Minecraft ne répondais plus alors je l'ai fermé et j'ai en vain relancé Minecraft mais il n'affiche que le logo de Mojang et répond pas ! J'ai relancé l'ordi plusieurs fois mais en vain ! AU SECOURS ! Je ne peux pas vivre sans Minecraft !


Rapport de l'erreur :
