Crash when you click "Presets" after replacing the "minecraft:plains" to a non-existent biome in the superflat customization menu
I was creating a world called "Nether" with Superflat, I replaced "minecraft:plains" to "minecraft:the_nether" to see if the piglins won't turn to zombified piglins, I clicked "Done" and clicked "Presets" again to see if "minecraft:the_nether" doesn't has turn onto "minecraft:plains" again, and The Game Crashed
What I expected to happen was:
When I click presets after replacing it, it should resets to default.
What happened was:
It crashed after I press presets.
How to reproduce:
Create a new world in Superflat click on Customize, after click on Presets replace the biome from "minecraft:plains" to a non-existent biome in the superflat customization menu after click on Done and Presets again and see if it crash(If you press cancel it won't crash)
Please provide more information about how you got this bug to happen
