IndexOutOfBoundsException error from Matrix plugin when handling packets

[thisisaef]

Describe the bug
When a player clicks in the interface window (such as a container window), the Matrix plugin catches an exception and throws an IndexOutOfBoundsException

Expected Behavior
The server should process the click event correctly, and the player should interact with the container without issues.

Actual Behavior
Instead of processing the click event, the server throws an IndexOutOfBoundsException, causing the player to be disconnected with the error message "Internal Exception: io.netty.handler.codec.DecoderException"

Steps to Reproduce

1. Have a player open a container window on the server.
2. Attempt to interact with the container (e.g., click on an item).
3. The exception occurs and the player gets disconnected.
