I got the same problem here but the path is a little bit different than everything listed, so hope it will help
1st One :
- I try to enter a created game
- nothing really happen, i don't enter any lobby, but every button except return get unusable
- but in fact, I can see in the back right corner that i joined the group
- I have to right click on my avatar an manually click quit the group
- then if I try to join a new game, nothing happen at all
- If i try to create a game, BF crashes with the same message than everybody.
(happened once, after leaving the group, i find several open games, with various persons as leader being in the one group i was in. included one opened game with me as a leader)
2nd one :
after restarting the game, i can etheir redo the path one or :
- I first create a game, without trying to join one, it works. I enter the lobby and can wait for other player.
- If i start the game, everything works fine. (i don't know if other player can see my game and if they can join, nobody came though)
- If I don't lunch and click return button, the game freeze or disconect. (Edit : If I use the Yellow cross, it close correctly with no freeze or disconect)
- But if I quit the game i just created and after it lunched, go back to map, i can then join other groups normally and play. (But I still can't create a game and click return button without freezing)
Log 1 and 2 are respectively for path 1 and 2 up to clicking return button.
Log 3 is for lunching the game, quitting, and then enter a group normally and do the whole mission
hope this will help.
