I have the same issue, if needed i can post logs, i dont have them atm.
But in my case i was playing ranked with concede after win, and after (i noticed this was random) either 4 games or 7 games the bot is still running but the win/lose screen (the one with stars/your rank/either victory or defeat text) it stays there and it does nothing, so one day i started my bot 10 in the morning, i got home 6 in the afternoon bot was still running, it had played 4 games and then stayed on that screen.
If i manually press the victory/defeat screen the bot continues like nothing happend, no errors or anything comes up, its more like it dosent register that it should go away from that screen.
