LottieAnimation.named() stalls the main thread

[44ron]

I use 4.5.0
Here's how I cache the animation:

guard let animation = LottieAnimation.named(Constants.myAnimationName) else { return }
DefaultAnimationCache.sharedCache.setAnimation(animation, forKey: Constants.myAnimationName)

Then i get it from the cache with
myAnimationView.animation = DefaultAnimationCache.sharedCache.animation(forKey:Constants.myAnimationName)

The main thread stalls all the same, just as if I've called LottieAnimation.named(Constants.myAnimationName) everywhere.
What am I doing wrong?
Is it even loading from cache that stalls the main thread (im starting to think it isn't)
