Xbox X serious FPS problem (witch summoner)

Hello,

I'm really enjoying the game.
However, I have a serious problem. I'm playing Witch Summoner on Xbox serie X, I'm lv79 with 15 minions, and the game literally runs at 10 fps, which unfortunately makes the game totally unplayable...
Are there any plans for a quick update to fix the performance problems?
Thanks in advance for your feedback.
