We're sorry for inconvenience. Exit Code:0 \". Vanilla minecraft works without problem. I tried reinstalling minecraft, forge, java. I tested it with and without mods with same result.\n \n\n\n\tdebug:\n \n\n\n\t[25maj2021 21:58:09.569] [main/INFO] [cpw.mods.modlauncher.Launcher/MODLAUNCHER]: ModLauncher running: args [--username,
