As soon as I open the Minecraft Bedrock Edition I can only write something once, because afterwards or while I am writing, a loading animation appears on the mouse pointer and then I can no longer write anything in the chat, both on private worlds and on servers. Sometimes the problem only hits after the message has been sent, the messages also arrive everywhere, only the further writing is prevented. I've already tested it with a texture pack and even without it, it doesn't work.
