Auldrick, you see, whenever I do that command in a EDU world and leave, I cannot speak in any other world, regardless of whether it is EDU or not. I cannot chat until I restart the game, go into that world, and do that command, then unmute myself. And when I said "log in" I meant start up the game. Sorry.

I am not sure, if this might help, but the /ability command can only be used, in education edition.
