I have one world (about 50 gb) stored on Xbox one.  After the 1.17 update, upon opening the app the screen is black for about 10 seconds, then the Minecraft symbol and "percent load" pops up.  Every time it gets to 89% and then can't get past it.  I have let sit for over 24 hours (loading),  have restarted the xbox multiple times, tried loading under different user profiles, and reduced the resolution on the TV.  Still stuck at 89% every time.
