FC24 slow menu, freezing and long loading times when searching for players

I have the exact same issue, it definitely ruins the experience of playing UT.

My game also freezing up randomly in UT menus just like what happened to you. It will freeze and had the FC loading animation on the bottom of the screen and then for a while the game will eventually kick me out. I now only do SBC on the webapp as it will definitely freeze up more often in the SBC section.
