ElNuza

So, yeah, since 2 days ago my game opens normally untill I enter any world, even if it is singleplayer or a server (any server from the modpack) and i´m not sure about why. I have tried to reboot my pc, turning off the firewall and nothing works even the game didn´t have any problems the day after thanks. (please help i have tried everything in my knowledge ;-; )
