Substance Plugin from Asset Store seems to break project?
I'm using Unity version 2018.4, I downloaded the latest Substance plugin from the asset store, and find myself utterly unable to get into my project.
All scenes are empty, and all prefabs are unable to opened, and give me the message: Failed to load 'Assets/xxxxxxx.prefab' because it was serialized with a newer version of Unity. (Has a higher SerializedFile version)
I think I've tried everything here, I've re-imported assets, reset packages to defaults, tried opening things in an earlier version, and I've downloaded the highest possible version of Unity and tried opening scenes and prefabs in that. There is no version control, so it doesn't have anything to do with that.
Can anyone help point me in the right direction to either resolve this or at least rescue the prefabs?
