Black screen and backround music after finishing game of conquest

1,5 years later this still happens to a lot of players.Only thing players can do is alt+f4 and restart the game. While your squad is already loading in. So they they have to back out of the game again. Because otherwise I will be in a queue for half of the game etc etc. 

It's an old bug, but apparently hard to fix, or it is being ignored.
