The game crashes (black screen) when I try to load a world

Hi @unknown 🙂 Do you mean MCPE closes every time you try to create a new creative flat world or every time you try to load some existing world you've previously played?

If it's an existing world, can you upload a copy for test?
If it's a new creative flat world, eeep! We'll need as much detail about your setup as you can provide. (New creative flat definitely works fine for many others!)

I fixed it. I forgot about this until now. My render distance was too high.
