When using the 'new-perlin-noise' branch (cannot be reproduced with the main 1.16.2 branch), Fabric API (dependency of Overworld Two) and either Phosphor Fabric v0.7.1 or MC-Lighting-Fixes, then the loading screen freezes at 0% and there is a log spam.

System/Minecraft:

• Minecraft 1.16.5
• Fabric Loader 0.11.3
• MultiMC 5 (0.6.12)
• Fabric API 0.32.5
• Windows 10
• AdoptOpenJDK 16 (OpenJ9)

Minecraft logs:

• With Phosphor: https://gist.github.com/DragonEggBedrockBreaking/94f2f55f3cc57a7e8b45d55e2cf61a5e
• With MC-Lighting-Fixes: https://gist.github.com/DragonEggBedrockBreaking/f71d798a35121e0e83dbc2babe2484cc

Code conflict in the ProtoChunk mixin.
