Minecraft MCPE isn’t loading properly

When I try to load MCPE, I’m met with a purple screen where the “Minecraft” loading screen would be. Then the main title screen won’t load, and when I press around when the buttons would be, the interface is bugged. Along with that, when I try to open a world or server, you can only see about 1/4th of the game. I genuinely cannot play Minecraft, nothing’s loading.
