What is your Bungeecord version? What is your Spigot server version? What is the client version?
Please add more details otherwise I won't be able to help you in any way.
Main server: git-Purpur-1858 (MC: 1.19.2) Pre-Lobby (login server) : git-Paper-790 (MC: 1.16.5) Proxy: git:Waterfall-Bootstrap:1.20-R0.2-SNAPSHOT:92b5149:562

This also happens on Paper-550 1.19.4 with a 1.19.4 client. I was able to reproduce this by renaming an item in an anvil.
I also have this problem, but when a player is in PVP and kills a person, it disconnects him from the proxy, unfortunately nothing appears in the log, I just deleted the plugin and everything worked correctly.
