But I seriously hope that someone who knows about custom chat systems can help with this because I am very desperate to get an answer on how to fix this without remaking it to basically be the ROBLOX’s default Bubble Chat but edited.
I don’t even know if this is a 100% the solution to this.
Disabling both classic and bubble chat will not fully disable Roblox’s chat system. It’ll affect the client’s ability to send messages but the backend will still be running. I don’t assume that’s what you want.
Turn off LoadDefaultChat to stop the Lua Chat System from being automatically added into your game. You can additionally use SetCoreGuiEnabled to get rid of the Chat buttons. From there, work your magic with your own chat system.
