Chunks don't load when generating with a view distance of more than 16

When creating a world with a view Distance of more than 16 chunks the generation fails. First it shows like 2 minutes "Building Terrain" BUT also shows the "Open Your Inventory" thing in the top right corner, and when it's finished chunks don't load and i'm in a nothing.

[Edit]: I also found out when clicking on "Save and Quit to Title" the game hangs and i have to stop mdm in the dubug console because i can't click on anything because i'm still in the game even if i switch the surface...
