Issue with player connecting to my server

Hi all, I'm trying to host a server for some friends and I'm able to connect, however my friend that's helping me test isn't.
She is constantly getting the "Internal Exception: io.netty.handler.codec.DecoderException: Unknown serializer type" with a random number at the end, so far we've seen 97, 111, 110, 116, 167, 105 from what I can recall.
We're hosing a 1.20.1 Forge server and made sure to have the exact same mods but nothing, I can connect fine but she joins and immediately gets disconnected with that error.
This is the log file she sent me but I wasn't able to deduce what the issue is: https://mclo.gs/TP90j44

From reading online it seems to be an issue with the Cobblemon mod but uninstalling it didn't help.
