Get errors and hang when using the BEPR biome on a 4 x 4 (1024) map.

I believe the screenshot has all the info you need but let me know if not. The error that seems to cause issues is the: MissingReferenceException: The object of type 'Terrain' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
GeNa.Core.GeNaMultiTerrainOperation.SetHeightmap (UnityEngine.RenderTexture newHeightmapRT) (at <b7d95d4594944bbf840a024a541df163>:0)

 

I did not delete any terrains. I simply asked it to spawn the biome.

Can you click on that error and see where its pointing to?

Can you try loading all the Gaia Scenes / Terrains at once and then apply the profile? 
Its saying that the Scene is not valid. 
Also check the build settings.
