This isnt a bug in general but its not working for me...

I use Forge Version 38.0.16 (not the newest but its 1.18.1) and the Server is on 1.18.1, im hosting the Server on Sparked Host (www.sparkedhost.com), on the Server is: More Villagers, Entchantments Descriptions, Skin Swapper, World Edit, Balm, JEI, Wonderful Enchantments, More Axelotles Variants Mod, waystones, gravestone mod, Emotecraft and Sit.
I used voicechat-forge-1.18.1-2.2.21 and put it in the Server Mods and in the Forge Mods and the server couldnt start and the Minecraft could start because of an error...

The crash report from the Server:

---- Minecraft Crash Report ----
// Surprise! Haha. Well, this is awkward.
