I have encounter the same bug too, but my game didn't crash. It is in ranked match making. I selected my hero (I was 3rd to select on my team). Then I was stuck in the load out. i.e. I tried to press the button 'enter battle as vengeful spirit', but it doesn't do anything. I tried to highlight other heroes and press the button, and it still doesn't do anything. And unfairly, I got abbaddon and lost mmr. match id: 1657415020.
