So I have tried to get Minecraft to open but it keeps crashing when it gets to the Minecraft loading screen with the bars at the bottom.

last Saturday I got Minecraft bedrock for my PC. Every time I try to open the game it gets up to a screen where it says Minecraft at the top, and at the bottom there is bars. at this point it crash's. Another thing, where you download the game, after I download it, it wants me to download it again.
