|---|---|---|---|
| Exit Code 1 | Generic crash on launch/load | Update Java to 21. Reinstall launcher. Delete .minecraft/config. | Use official Minecraft launcher. |
| OutOfMemoryError | Lag then crash in big worlds | Allocate 4-8GB RAM in launcher settings (JVM args: -Xmx4G). | Close background apps. Use Sodium mod for optimization. |
| Mod Loader Crash (Fabric/Forge) | Crashes post-mod install | Match mod loader version to Minecraft (e.g., Fabric 0.16+ for 1.21). Run /mods check. | Test mods one-by-one. |
| Shader/OptiFine Fail | Black screen or instant CTD | Switch to Iris Shaders + Sodium. Update OptiFine to preview for 1.21.1. | Lower render distance to 12 chunks. |
