I have been playing a modded Minecraft pack for the past week and it has been fine. I go to to get on the other day and it crashed with exit code 1. I tried many more times to relaunch it and it kept saying the same thing. I looked for abount a hour on the internet to find any solutions to the problem and saw that reinstalling java may help. So I tried that and it did not work. I tried updating my Nvidia drivers and that did not work. I tried launching Minecraft in the vanilla version that my modded pack was on becuase I have never launched it before. That did not work either, but it did change the way the game "crashed". Instead of the game crashing with exit code 1, it just pops up the launcher for a second like its launching except it never does.
