This crash is caused by a mixin conflict between two mods: Entity Texture Features and ImmediatelyFast.
The crash occurs during game initialization when Entity Texture Features tries to modify a method in ImmediatelyFast's BatchableBufferSource class, but can't find the target method it's trying to modify.
