Setting up the server modpack for a friend and she keeps receiving the error "Internal Exception: io.netty.handler.codec.DecoderException: Failed to decode packet 'clientbound/minecraft:custom_payload'

I've been digging around and there's not been much help for this issue beyond saying to use Packet Fixer. This has its own problems since I've got it downloaded onto the server side as well as her side, yet it seems the server isn't reading the mod for some reason.

Server Info
- 1.21.1

- Fabric launcher

- moderately modded

- friend has no mods that are incompatible with the server

Error code shortly after loading onto the server
