Hi @7Dev.io, I had a first look at that issue and I did not get a crash to desktop, but I did get the same stack trace as you have as error message in the console, with the new terrain layer not being added to the terrain. It looks like - similar to the crash you originally reported for the beta version of 2022.2 - that there were fundamental changes in the serialization code of the unity editor which disturb asset creation from code in parts of Gaia which were working without problems in earlier unity versions.
This might potentially be a bug in the new version 2022.2 as the behavior is very erratic - the crash you originally reported was caused by us creating a terrain data object during terrain creation (which is pretty much a requirement) but only when there was a call to Resources.UnloadUnusedAssets() before - this has never been a problem in any editor version before and this might not be intentional.

While we investigate this some more, you could do one of the following as a workaround:
 

• Use an earlier unity version (you should not encounter this crash / issue there when adding a new texture spawn rule)
• Add the terrain layer to the terrain manually, then pull it into the spawner with the "Add Resources from Terrain" feature here:
  
  
  Tread with care as this will reset the mask setup for your spawn rules for the already existing spawn rules in the spawner.
• Create the new spawn rule as usual, but then add a terrain layer with the same textures to the terrain manually from the terrain inspector. This should prevent the issue from occurring as Gaia will not try to add the terrain layer anymore if a layer with the same textures is already present
