Also, I tried the above steps, but they did not work for me as I am on Windows 10 on pc and the above steps only work on mobile.
Whenever I boot up minecraft windows 10, I am greeted with the scrolling background image, but no UI. If I click in the general vicinity of the buttons, I hear the button clicking sound, but I see no changes. I can even open up a game if I click the correct invisible buttons, but when the world boots up, it is corrupted (i.e. all I see is a mesh of polygons all over the screen) I can still move around and jump, but there is no comprehensible image.
I have tried uninstalling and reinstalling as well as rebooting my computer.
I have tried playing just by randomly clicking hoping i land on the right button. I have managed to get in game and have attached pictures of what I saw.
