Besoin d'aide pour installation backpack...

Bonjour, je débute dans l'installation de Mods et d'ailleurs je n'y connais pas grand chose. Je joue depuis peu de temps à minecraft et pour le moment le seul mod à m'intéresser est le BACKPACK. Mais j'aurais besoin d'aide svp...

J'ai suivi un tuto pour installer forge, et cela s'est bien passer, installer avec succès, le jeu démarre sans problème.

Ca se gâte quand j'installe le fameux backpack... Pareil je suis le tuto, rien de sorcier : le télécharger et mettre directement l'executable dans le dossier mods de .minecraft.
Mais là le jeu crash à chaque fois pdt l'installation et du coup, n'étant pas très douée ni en anglais ni en informatique je ne sais pas trop quoi faire...

Je joue sur minecraft 1.10.2, Shiginima Launcher SE v3.100.

Voilà le rapport de crash : (je ne sais pas si je dois le mettre en entier, donc au cas où...) :
