Whenever I try to launch a co-op game, it starts the count-down, goes to a black screen, music is playing and then it kicks me back to the menu. I tried joining my friend, thinking it was a host issue but the results remain the same. The issue appeared ever since the latest update.
I have the same Issue, i verified Game Files,unistalled Javelin and reinstalled it.
Worked for one Match and then again to the same Error as the OP
Whenever i uninstall and reinstall Javelin i can play for 1 Match
since today i receive the same issue by trying to enter a breakthrough official server via matchmaking:
countdown, black screen, pushes me back to main menu
yesterday everything seemed fine, and no any updates have been applied since yesterday
and official conquest heavily rubberbands as i have just explained in a seperated thread
EDIT:
same issue now happens on official conquest too. i am verifying steam files now and manually update javelin afterwards
