Error when I try to access my server with the version 1.20.4 of minecraft

[IL25-code]

Describe the bug When I add the plugin Plugin Hider Pro it gives an exception and I can't join the server. I contacted them and they told me to contact you. However I can't join with the version 1.20.4 but I can join with almost any other version like 1.20

The exception is: io.netty.handler.codec.DecoderException: java.io.IOException: Packet configuration/0 (xj) was larger than I expected, found 479 bytes extra whilst reading packet 0.
