Screen gone black when software update.

Hi! My Xs Max screen gone black when I was updating new 13.4.1 software. Any idea how get my phone screen back. I tried hard restart but it doesn’t work. I keep charging and left for few hours but still not work. I can feel vibrations and siri work sometimes and also able to receive call but can’t see anything. Please look at the images and time. I also have video but couldn’t post here. Please provide me the best help. Thanks
