I did not get the biome registry error message but my biome is not showing up in the world btw I tried biome locate command
I have that same issue I get an error saying get biome registry error in my logs
I did and that error still popped up.
what should happen is that my custom biome should generate with no error about biome registry.
btw it also happens if you place the block down in non-deferred render and reenabling it
