The game freezes when started.

What I expected to happen was...:
click on the game tile in windows 10, click options, set the difficulty option, then click out and click play and the world screen come up and into the game. And it all happen straight away, like any other game does.

What actually happened was...:
I Clicked the game tile, the MOJANG label came up, then the start screen. I moved the cursor over the start or option tiles and nothing happened instead of it going blue and yellow straight away. I clicked on the start button and it took about 30 seconds for it to make a click sound and another 45 seconds to go into the world screen, or 60 seconds to go into the options screen. I spent about 15 min's just to get to the next screen from the world screen.

Steps to Reproduce:
1. Go into APP store widows 10, and download Minecraft widows 10 edition Beta
2. Click on the game to run it.
3. click start or options.
