Can't access friends list or chat window on Steam client

So I'm having a weird problem which has lasted for a few days now. The friends list is open in Steam but whenever I click on it to bring it to the front and view it, nothing happens. As in, there's a window open for the friends list but no way to access it so I've had to resort to using the browser chat which isn't much of a workaround and I still can't access group chats and all the features of the chat window. I've already restarted Steam and my computer but neither fixed it. Is anyone else experiencing this? I'm on Steam beta so perhaps it's a problem with an update, any help is appreciated.

EDIT: It's gotten worse, now I can't even use Steam chat.
