play button dissapeared (client)

Hello guys, today i wanted to play a game. Before that i spectated a match of my friend C4pit4nul. He told me on a social media site that he ended the match and that i need to get out from spectating it. The match was still on loading screen. I pressed Alt+f4 to get out from spectating faster. When i got back in the game the play button and all others dissapeared. I tried a full repair but it didnt work. All that i can see is the friend list and the arcade screen and it still shows me that i am spectating something even if i spectate nothing.

Can someone help me?
