Bug No Script Asset for SpriteLibCombineCashe error

So I tried to google this but only found one thread from 2016 and it seems they never got it figured out! TvT


I am using the Sprite Library (alongside Sprite Renderer / Sprite Resolver / Animator) and every time I add a new entry into a category I get this error.
- I have Unity 2021.1.7f1
- I get this error even with animations/everything else set up and working!
- It only happens when the game is run and the object with the sprite library is selected!
- This is replicable for me on a brand new project!
- I get this error even when this is the only component or with all components active and fleshed out!
