Old World Type doesn't load correctly and gets stuck at "Loading Terrain" forever.

After 1.17 Update, I can't create a new Old World Type on bedrock. Maybe the new terrain generation is to blame but im not sure. I tried reinstalling the game, clearing its data, i just can't add a new Old World Type. Are you planning to remove the option to create one in the future? My device can't really render infinite world really well so i hope there's a fix.
