This is a known bug which I believe is only occuring in certain devices. There is currently no way to fix it, we need to wait for a fix from Niantic. I have the same bug myself, sometimes however it does let me open it and sometimes it doesn't. The game also freezes if you open any Pokémon next to it on either side. If you want to transfer it just try it once in a while and sometimes you might be able to open it without the game freezing. Other than that, there isn't really anything you can do about it for now.
