    Outdated mods = error central. Head to CurseForge or Modrinth:

    • Specifically update Guide-API, Patchouli, and any gem-related mods.

    • Avoid over 16GB unless you have 32GB system RAM.
    Relaunch and test a new world.
  3. 🗑️ Clear Cache & Configs
    Corrupted files are culprits #1.
    • Go to %appdata%\.minecraft\config (Windows) or equivalent.
    • Delete folders for Guide-API, Patchouli, and your modpack.
    • Also nuke shaderpacks and resourcepacks if using.
