I have already reached out to support about the issue, however, I am posting this here as well so you all know and can be made aware of the massive bug that almost bricked my TV. I was playing Countdown on Xbox Series X and as I left I got that loading bug where it loads to 100% while jittering on the screen. I have seen others have the same bug. However I sat there for like 2 mins before stopping it and when I did, the circle was still there burned into the screen.
I turned off the tv, did a hard power reset of the TV and the circle was still there. Took about 10 mins for it to finally clear off the TV. So if you get that bug, immediately restart the game. Do not take a chance of having it brick your TV. Be careful......
