[Bug] Unable to join server with more than 1 player online

[SakuraKoi]

Minecraft version: 1.20.1
Mod version: visualoverhaul-forge-5.0.1

When the server is empty, everything is fine.
When there is already at least 1 player online, new players joining will be disconnected due to a packet decoder exception.
