During async loading from an AsyncLoading thread, DecalComponent attempts to precache PSOs which can trigger a checkf in StrongObjectPtr.h which are only allowed to be created on a game thread.
No confirmed repro steps exist, but most likely this requires loading a level with numerous decals in a game client with PSO Precaching and async loading enabled. It may also require spawning decals at runtime.
