Game Crashes When Using On-Tick Procedure in Custom GUI

Hi everyone,

I'm working on a Minecraft mod using MCreator and NeoForge 1.20.4. I've created a custom GUI and implemented an on-tick procedure to check the inputs and enable or disable buttons accordingly.

The issue arises when I press a button in the GUI. The game crashes, and the error message indicates a ClassCastException. Removing the on-tick procedure seems to fix the crash, but I need this procedure to function correctly. Here is the relevant error message:

[02:32:12] [Netty Server IO #1/ERROR] [minecraft/Connection]: Received class net.minecraft.network.protocol.common.ServerboundCustomPayloadPacket that couldn't be processed 
java.lang.ClassCastException: class ....network.OverviewGUIButtonMessage cannot be cast to class ....world.inventory.OverviewGUIMenu$OverviewGUIOtherMessage (....network.OverviewGUIButtonMessage and ....world.inventory.OverviewGUIMenu$OverviewGUIOtherMessage are in module testmod@1.0.0 of loader 'TRANSFORMER' @4f8d86e4)
...
[02:32:12] [Server thread/INFO] [minecraft/ServerGamePacketListenerImpl]: Dev lost connection: Server sent an invalid packet

I want to note that this is not due to the button press procedure as even if its empty it still crashes, this happened to me with also another mod where I had an on effect active tick procedure but when I cleared the effect it crashed, however just letting it expire naturally doesnt crash it, just like closing this gui with esc also doesnt crash it.
