oops we were unable to start a game for you

Well first of all I do not know if the problem I faced is related to HB strictly, but I have never ever had the problem like this. I've been using HB for 2 weeks now and yesterday when I started to bot I had several hearthstone crashes, sometimes after 1 game (mostly) sometimes after more than 1. I assume the problem is connected with HB, I tried to google it and the some guy were telling it is because of background applications. How can I solve the issue?
Thanks in advance
