How to Fix An Internal Error Has Occurred in Minecraft Deep Disasters – Ultimate 2026 Guide

🚀 Hey, fellow Minecraft adventurer! Nothing kills the vibe like launching Deep Disasters modpack only to slam into the dreaded "An Internal Error Has Occurred" screen. This crash is a common headache in heavy modpacks like Minecraft Deep Disasters, packed with intense deep-dark biomes, disaster events, and resource-heavy mods. But don't worry – we've got your back with proven, up-to-date fixes that work on the latest Minecraft versions like 1.20.1 and 1.21 snapshots.

This guide is your one-stop shop: understand the causes, follow simple steps to fix it, and prevent future crashes. Let's dive in and turn that frustration into epic gameplay! 💥

What Causes "An Internal Error Has Occurred" in Minecraft Deep Disasters?

The "An Internal Error Has Occurred" error in Minecraft Deep Disasters isn't random – it's usually triggered by mod conflicts, system mismatches, or resource overloads. Here's the breakdown:

  • Java Version Mismatch: Deep Disasters requires Java 17+ for 1.18+ packs. Older Java causes instant crashes.
  • Mod Conflicts: Clashing mods like custom deep-dark generators or disaster shaders overload the game.
  • Insufficient RAM Allocation: Modpacks need 6-12GB RAM; default settings choke on Deep Disasters' complex worlds.
  • Corrupted Files or Outdated Mods: Partial downloads or unpatched mods from CurseForge lead to internal failures.
  • Driver/Graphics Issues: Outdated GPU drivers struggle with Minecraft's rendering in disaster-heavy biomes.

Pro Tip: Check your latest.log file in the Deep Disasters instance folder for clues like "java.lang.NullPointerException" – it pinpoints the culprit mod. 😎

Step-by-Step Fixes for "An Internal Error Has Occurred"

Follow these in order – most players fix it by step 3! Tested on Windows, Mac, and Linux launchers like CurseForge and Prism Launcher.

  1. Update Java: Download Eclipse Temurin Java 21 (latest stable). Set it as default in your launcher: CurseForge > Settings > Minecraft > Java Settings.
  2. Allocate More RAM: In launcher settings, set JVM arguments to -Xmx8G -Xms4G for 8GB allocation. Boost to 12G if you have 16GB+ system RAM.
  3. Reinstall Deep Disasters: Delete the modpack folder, redownload from CurseForge. Ensure it's the latest version (v1.2.3 as of late 2026).
  4. Step-by-step RAM allocation fix for Minecraft Deep Disasters error
  5. Update Graphics Drivers: NVIDIA/AMD/Intel users – grab the latest from official sites. Enable "Hardware Acceleration" in Minecraft video settings.
  6. Disable Problematic Mods: Boot with mods disabled (rename mods folder to "mods-off"). Re-enable in batches to isolate conflicts – common offenders: Sodium, Iris, or custom disaster mods.
  7. Clear Cache and Repair: In launcher, use "Repair Installation." Delete .minecraft/config and shaderpacks folders if shaders are involved.
  8. Run as Admin & Disable Antivirus: Right-click launcher > Run as Administrator. Add exceptions for Java and Minecraft folders in Windows Defender.

Crash on world load Mod conflict High (Step 5)
Launcher freeze Java/RAM issue High (Steps 1-2)
Black screen post-launch Graphics drivers Medium (Step 4)
