emacs GUI freezes when using Font Awesome 5 icons

When I insert an icon in Font Awesome 5, the emacs GUI freezes. This does not happen when using emacs -nw, and icons displayed correctly in emacs -nw I do have Font Awesome 5 in my .font folder

The music still running is only loosely related to emacs, because emms spawns an external mpv(or whatever music player it can find) process to handle that :)

Oh ya, I forget that I set the default player to mpv, sorry about that
