Preliminary Fast Checks

Verify these 3 simple prerequisites before proceeding to in-depth fixes:

DEEP DIVE

🔬 Root Cause: Why Does Exit Code 0 Occur?

Minecraft Exit Code 0 is a general crash indication from the Java Virtual Machine. It means the Minecraft Java runtime crashed without generating a specific unhandled exception code, typically caused by display driver OpenGL failure or mod version mismatches.

🔍 Primary Triggers for Exit Code 0

Incompatible or outdated Forge / Fabric mods in the .minecraft/mods folder.
Outdated graphics drivers failing to initialize the LWJGL OpenGL window.
Insufficient RAM allocated in Minecraft Launcher Java arguments.
Corrupted options.txt configuration file.

⚠️ CRITICAL WARNING

What NOT to Do

Do not allocate all your PC's RAM to Minecraft; always leave at least 4GB of RAM for Windows operating system processes.

Complete Step-by-Step Solutions for Exit Code 0

Execute these verified methods sequentially from easiest to most advanced:

Temporarily Move the Mods Folder

Isolate whether third-party mods are causing the JVM crash.

Press Win + R, type '%appdata%\.minecraft', press Enter. Drag the 'mods' folder to your desktop, and try launching Minecraft. If it launches, one of your mods is incompatible.

Allocate Optimal RAM in Minecraft Launcher

Prevent out-of-memory JVM heap crashes.

Open Minecraft Launcher > Installations tab > click the three dots (...) on your profile > Edit > More Options > in 'JVM Arguments', change '-Xmx2G' to '-Xmx4G' (for 4GB RAM) or '-Xmx6G' > click Save.

Delete Corrupted options.txt File

Reset video settings to default without losing your worlds.

In %appdata%\.minecraft, locate 'options.txt' and delete it. Minecraft will regenerate a clean settings file upon next launch.

PRO TIPS

💡 How to Prevent Exit Code 0 In the Future

Use modern mod launchers like Prism Launcher or CurseForge App to prevent mod dependency conflicts.
Keep Java 17 or Java 21 runtimes updated.
