@112 Sorry to hear you're facing troubles. Unfortunately we can't help based on such a screenshot alone.

Which version of the spine-unity runtime (name of the unitypackage, also listed in Assets/Spine/tersion.txt, or alternatively the version in the Unity Package Manager) are you using?

What did you do that led to this issue?
What code is executed that lets this issue occur?

112 I had this problem after the character switch animation following the dynamic replacement of skeletonDataAsset

Then you're likely doing something wrong in your code that is switching the SkeletonDataAsset at your SkeletonAnimation component. Without seeing it we are still unable to help though.
