If I may, I would just like to add to a temporary "fix" that a user found on previous pages, which was after enter the game, go to "User Center" and wait for 5-7 minutes. After this wait, the game works fine, and in fact, I managed to play for 6 hours without major problems on BlueStacks.
HOWEVER, this method doesn't work for everyone; some reported that even after doing this, the problem persisted.
