NullPointerException in Forge Event Bus — OptiFine Conflict
OptiFine is overriding Forge's rendering pipeline in a way that causes a null reference when the `ChunkRenderDispatcher` initializes during world load. This is a known compatibility issue with certain OptiFine versions and rendering-heavy mods.
Affected mods:
Fix steps:
- 1Downgrade OptiFine to HD_U_I5 or switch to Sodium + Iris for better compatibility
- 2Remove conflicting shader pack temporarily to isolate the issue
- 3Add -Dfml.ignoreInvalidMinecraftCertificates=true to JVM args
