ProtocolLib compatibility creates a massive error upon joining.

[Pixelcraftian]

What happened?

ProtocolLib and CustomCrafting being on the same server is not friendly to people joining. Spits out a massive error whenever somebody joins. Doesn't happen on disconnect. Both configs have not been modified to my knowledge.

(There is a closed issue along these lines but it's a different error and there was no outcome)

How can the bug be reproduced?

Have the plugins installed on the same server and join.

Expected Behaviour?

This error should not appear.

Plugin version

CC 4.17-beta.5, WS 4.17.0.0 - PL 5.4.0-SNAPSHOT-738

Server software

Paper 1.21.3

I just got this issue as well, but it happened due to a player leaving, a moment after their UUID was saved. Using 1.21.4 purpur, plugin version is 4.16.11
