Need help with an error I have a custom modpack that I have made, my other friends have been able to play it without a problem. However one of my friends is unable to run the modpack. From my understanding, the modpack loads and tries to open the MC client, is unable to open the MC client, and crashes back to Technic launcher. He has a 64 bit version of Java and is allowing Technic launcher GB of RAM (my modpack uses usually 1.5GB max) My modpack: https://www.technicpack.net/modpack/godsquad-pack.1577263 The full crash report my friend gave me: https://pastebin.com/Fht29Bsa
