Freezing and No Response

When entering Minecraft For Windows 10 I seem to be having some issues in some on the menus. These include freezing/no response on the start menu, when creating a new world, entering the store, and finally when trying to load an already created world. I just started using Windows 10 a few months ago and decided to try out Minecraft. After the first few versions everything was perfectly fine. When I started encountering these issues were during my experience of V1.5 and V1.51. I first tried to enter the Minecraft store to purchases a few things. It wouldn't respond at all unless I pressed Ctrl + Alt +Esc or turned off my computer entirely. After this I started having the same issue when trying to create a new world to play in or trying to play an already created world.

Thank you for your time and help with everything that you give! I hope you can find a solution to this bug!

Sicerely, Izaha Mercier
