Unity3D Null Reference Exception

[CasulScrub]

I am having this null reference thrown very randomly, so it is hard to trace the cause. I am using Unity 2018.3. It stops my animations from playing.
NullReferenceException: Object reference not set to an instance of an object DragonBones.AnimationState.AdvanceTime (Single passedTime, Single cacheFrameRate) (at Assets/DragonBones/Scripts/animation/AnimationState.cs:951

This error also occurs randomly, switching between scenes.
