Samsung Galaxy S4 - new 4.3 release still has bugs smh

[Perone Harris]

I just downloaded 4.3 on my galaxy s4 and when I go into my app drawer and go into my menu to disable applications then choose to show those disabled applications it freezes for a few seconds, shows a black screen then says, "Unfortunately touchwiz home has stopped"...WTF any help?? I also don't understand why I cant see my hangouts icon anywhere smh...
