no error on 1.21.4 with labymodPlayer

what do you mean "no code". there has to be some code which fails. The error you sent indicates that either the player you tried to set the subtitle for does not use LabyMod or that the protocol did not receive the packets to identify the player yet.

and you are sure that the player you're trying to access is online with LabyMod? because LabyModPlayer instances are always null for non LabyMod players. so maybe consider adding a null check

[vertraxumtesOG]

Yes He is online with laby. In 1.21.4 it works, in 1.21.5 it isnt working.
