How to reproduce

on player join
on player leave
or at random times

Platform

• Server version (output of /version): 1.16.4 paper 388
• Holographic Displays version (check with /hd): 2.4.5
• ProtocolLib version, if installed (check with /protocol version): #492
• Do you use plugins to allow players to join with multiple Minecraft versions (such as ViaVersion, ProtocolSupport, ...): viaversion

Additional context

Seems like incompatibility with this ProtocolLib change: https://github.com/dmulloy2/ProtocolLib/commit/b54dd49426f1c4cb5a15d1702a4803af1846847e

The last ProtocolLib build which is not affected is #490

Duplicate of #388 (keeping the most detailed one)
