Profiler spikes of Loading.LoadFileHeaders inside Animator.Update in the Unity Editor

Question

alt text

When I open Unity Editor and start playing scenes with GameObjects w$$anonymous$$ch use Animator I get spikes from Animator.Update -> Dirty Scene Objects -> Loading.ReadObject -> Loading.LoadFileHeaders. And it is almost impossible to play, but the curious t$$anonymous$$ng is that those spikes eventually disappear w$$anonymous$$le I continue playing the scene for a long time. And the spikes are not present in builds.

I wonder if somebody knows what could be the cause of calling to Animator.Update -> Dirty Scene Objects -> Loading.ReadObject -> Loading.LoadFileHeaders.

Try enabling read/write on all of your animations.... might work.

Nope its not that, disable write defaults on all of your animators, that's the one.

Not sure what to do. I have same problem, its breaking my project.

T$$anonymous$$s could be related to missing components or missing links on your animations, prefabs, etc... There are some bugs also related to t$$anonymous$$s:
