[1.19.4] ProtocolLibrary.getProtocolManager() returning null

[lollolcheese123]

Problem Description
Whenever I try to use ProtocolLib's ProtocolLibrary.getProtocolManager() code it always gives me a NullPointerException

API method(s) used
ProtocolLibrary.getProtocolManager
.createPacket(PacketType.Play.Server.BLOCK_BREAK_ANIMATION);

Expected behavior
Obviously I expected to get the ProtocolManager class object, to be able to use ProtocolLib

Additional context
I am using IntellijIdea
