Problem Description


For the Dawncraft modpack on curseforge, unsure on what to do. Got a similar message with trying to run All The Mods 9 this morning. I have ensured that the version was the same as selected during configuration of instance.

Console returns:
Error: Could not find or load main class

Reproduction Steps

  • Configured Instance to Forge 1.18.2
  • Added the forge 1.18.2 Zip into the mods folder
  • Added the Server zip for the modpack into the mods folder.
