I use neovim in tmux for development and have set up as a keymap for cmp completion. It was working well until just a while ago and I don't know what happened.
seems to register as a simple when I'm under tmux and so doesn't cmp complete in neovim. It's not a problem with cmp as is also bound to that and it does work. It also isn't a problem with neovim or the terminal emulator itself, as I tried this on foot, alacritty, kitty and gnome-terminal. In all cases, works when not in tmux, but when tmux it doesn't work.
It was working fine just yesterday, and I don't know why it isn't now or how to fix it.
Has anyone had this kind of issue or knows how to fix it?

I don't think it's a config issue as I haven't changed it for months now
