Ok So i hopped on here to see if anyone can give me some insight, I've been trying to fix this issue for two days for my little bother to no avail. So whenever he starts a modpack (or the vanilla minecraft launcher) it loads up but when the game is supposed to open it just closes technic (or mojangs launcher) and restarts it, ill include the log file it is not a ram issue cause i have 7 GIGS ALLOCATED. Please help thank you.
