You got this error: minecraft:root/minecraft:worldgen/biome: Unbound values in registry ResourceKey[minecraft:root / minecraft:worldgen/biome]: [mitems:flowbiome]

You might just need to regenerate the base mod source files and build the gradle project again (The Hammer Icon). It was most likely caused by a biome you deleted still being in your mods files. After regenerating close mcreator, load it back up and retry creating a world.
