[14:39:40] [Render thread/WARN]: Client disconnected with reason: Network Protocol Error

Uninstalling No Chat Reports fixes this issue and the client is able to join the server no problem.

To Reproduce

1. Install No Chat Reports: https://modrinth.com/mod/qQyHxfxd
2. Join server.
3. Pumpkin logs that the player immediately leaves and error is thrown on the client above.

Expected behavior

Join server without it throwing Network Protocol Error.

Maybe its because Pumpkin currently does not initialize secure chat
