I have a 1.12.2 modpack that I haven't played in about a year, and today I tried to load it up, but it crashed immediately, before the Minecraft window even opened. I'm pretty sure I haven't changed anything since I last played it, except maybe update Java, but I tried several different versions of Java and it did the same thing. I'm using Forge-1.12.2-14.23.5.2768, which is the recommended version.
