Discord causes EXWM to call `(select window nil)`, which errors

[LemonBreezes]

Hello. For some reason, when I start Discord, I get a window-live-p nil error. I investigated by adding this advice:

(defun +exwm-select-window-a (oldfun window &rest args)
  (if window (apply oldfun window args)
    (backtrace)))
(advice-add #'select-window :around #'+exwm-select-window-a)

and here are some of the backtraces I've gotten

  backtrace()

select-window is invoked in _NET_ACTIVE_WINDOW handling. If EXWM receives such a request for a window it does not manage, it will fail. Does discord show a splash screen or similar?

Yup. That's exactly what happens.

Just in case you're still having this issue or someone else is make sure you're launching discord with the async-shell-command as it says in the guide.

I found launching discord any other way(counsel-linux-app etc) just gave off this error and would not allow the window to open.
