Challenge Bug (UI dissapears, not working buttons or menu) + (Invisible users)

I cant literally play the game. This bug has happened to me in the last 2 days, when i want to start a challenge, my UI dissapears, the challenge does not start, every interaction does not work, even menu. I have to forcely shut down the game and restart it, just for it to happen again. 

Also the invisible bug is triggering me, as soon as i teleport to someone, everyone becomes invisible to me, not even usernames. I seen posts of people saying that spectating someone ang getting back resolves the problem but not for me, it is just me alone in the city + not even be able to do challenges.

Im a big fan of the skate series but i just cant have fun restarting my game 3 times in an hour. Hope this gets resolve asap. Big love and keep progressing.
