I had similar issues after the update, end of round screen had black/ no background, none of the player profie pics were showing just a box were it should be, I couldn't even see what I got when I opened a battlepack, however I found this fix for Xbox (may be similar on ps4) quit the game, go to xbox home screen, hover over game icon, press the right MENU button and move down to "manage game" move down the left list to saved data, move right and down to "reserved space" and press A, select "clear reserved space" and press A again, then go back and lauch the game again, you will find this will clear all your black screen issues.
