Hi,

I assume that this is not a problem of ProtocolLib itself but rather one of your other plugins that is incompatible with the latest Minecraft protocol. Please send us the output of /protocol dump (which includes a list of all your plugins and how they interact with ProtocolLib) and any exceptions / errors and relevant warnings that show in your log file.

If anyone is curious, this seems to be related to Minecraft changing how JSON components work.

Specifically, net.kyori:adventure-text-serializer-gson:4.3.0 is compatible with Minecraft 1.19.4, but net.kyori:adventure-text-serializer-gson:4.17.0 isn't (I haven't bisected the exact version, nor do I intend to).
