Problem Description

Issue

Everytime we try to load forge world it does not work on 1.20.1 even without mods just the forge doesnt work at all.

Reproduction Steps

  • create instance
  • go to configuration
  • change to forge’
  • click on 1.20.1 latest version
  • update and download the forge version

What exactly doesn’t work? Does the server boot? Can you join it? Is it a vanilla world/server?
