"The type or namespace name 'ScriptableSingleton<>' could not be found" error on build

[enitimeago]

Upon debugging why a friend's avatar was not building with MA 1.8.4 and NDMF 1.3.2 in Unity 2022, I noticed in their logs:

Packages\nadena.dev.ndmf\Runtime\NonPersistentConfig.cs(6,42): error CS0246: The type or namespace name 'ScriptableSingleton<>' could not be found (are you missing a using directive or an assembly reference?)

The friend was able to build their avatar once I requested them to downgrade NDMF to 1.3.1.

Inspecting 2896716, could the source of the issue be that NonPersistentConfig was moved from an editor assembly to a runtime assembly, since ScriptableSingleton is a class under UnityEditor?

Log filtered to errors:

Thanks for the report, this was indeed the problem. I'll have to build some additional CI steps to catch this issue...

Thanks for the really quick fix!

I can verify on my own side in Unity 2019 that 1.3.2 broke builds and that I can build again with 1.3.3.
