Bug Description

When joining with MC (Badlion in my Case idk) 1.20.4 on a Spigot 1.20.5 Server some Players get following Error (picture). We have 2 Players on the Server where IT doesn't Work they both have Numbers in their Name. Our other members do Not have Numbers in their Name and can Join. There is No Problem when joining with 1.20.5

Also If joining in another Version, If you Type you get kicked with "Chat validation Error".

Steps to Reproduce

Login in into the Server with 1.20.5 to get kicked

Expected Behavior

Don't get kicked when you Join or Type a message

Additional Server Info

I use spigot 1.20.5 on an Aternos Server, and IT happend after we Upgraded to 1.20.5, i already tried reinstalling etc. We don't use a proxy

Checklist

• [X] Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. BungeeCord), not on both.
• [X] I have included a ViaVersion dump.
• [X] If applicable, I have included a paste (not a screenshot) of the error.
• [X] I have tried a build from https://ci.viaversion.com/ and the issue still persists.

I am getting the same problem. Just to confirm it for you

[Kichura]

Can you test this with just via* plugins active to see if problems continue to happen + And also paper 1.20.4 as second server for testing?

I am getting a similar issue on a 1.21 server with viabackwards, when any player with trimed armor (any trims, not just 1.21 trims), I get kicked with a similar error. I play in 1.20.2

The original issue shouldn't happen on the latest release, everything below that would be different issues
