Describe the bug
I installed viaversion and viabackwards on bungeecord
Today I updated viaversion and viabackwards to 4.8.1 in order to support 1.20.2 players entering my server
My subserver is on spigot 1.18.2. I user 1.20.2 and tried to enter, but the server kicked me out

This is the log: https://justpaste.it/7xwws
and the dump information: https://dump.viaversion.com/138251e117317f252e4b928bf36029db68f25134b751a407eb949b50f8452e88

To Reproduce
install ProtocolLib on subserver
install viaversion and viabackwards on bungeecord
start the two servers
join the server
