โœ… What Causes Forge Exit Code 1 Minecraft Error: Mod Mixups?

The Exit Code 1 pops up when Java can't initialize your game due to mod mayhem. Here's the top culprits in Mod Mixups:

  • Version Mismatches: Mods built for Forge 1.19.x won't play nice with 1.21.
  • Duplicate Mods: Same mod in different folders or versions causes overload.
  • Incompatible Pairs: Think Sodium + OptiFine โ€“ classic rivals!
  • Corrupted Files: Bad downloads or partial updates.
  • RAM/ Java Issues: Not enough allocated memory for heavy modpacks.

Pro tip: Check your latest.log in the Minecraft logs folder. Search for "Mod Mixups" or red error lines pointing to specific mods. This pinpoints the villain! ๐Ÿ”
