I've got exactly the same issue. Had it during the Beta too. Super disappointing. If anyone knows of or finds a fix please let me know.
I was able to get into a initiation breakthrough match earlier, but after trying again later with Conquest, the same thing started happening again. I'm over it. I'm going to try and get a refund.
I got into a match for a few minutes last night after playing menus with my friends in the party. Restarted when I thought it was fixed and continued to have the same issue. My friend joined a match every time. When I tried to join him, it still said that he was in my party. I've tried deleting the multiplayer aspects of the game in the library and reinstalling them and still no joy. What's really frustrating is that there is no error code or acknowledgement that it's not working. Start a game, some time goes by, the avatar stands up, music changes, black screen then a battlefield splash screen and returned to lobby... Expected so much more. Been playing the series of games for nearly 20 years. Battlefield, Battlefield 2,3,4. Bad Company etc etc...properly let down!
