Lost Avatar, Worlds Not Displaying 26.50/26.51

I updated to 26.50 yesterday (Sept. 16) morning. When I started the program, my avatar flickered for an instant and then disappeared. I can access the dressing room but avatar/skin is missing. When hitting “Play”, the menu buttons disappear and leaves a rotating scenic view with no worlds or buttons to select. Clicking in the space on the screen where my world would be gives a selection click but nothing happens. On this rotating screen I have to force close Minecraft because I cannot exit this any other way. Updated to 26.51 hotfix - same problem repeats exactly. I am on an iPad Pro 12.9” (6th edition) running IOS 26.6.1.
