### Steps to reproduce (from fresh new project)
Steps to reproduce `ERROR: Condition "skeleton->size == 0" is true. Returning: RID()` error.
1. Create new project.
1.1 Godot version used: v4.1.beta2.mono.official [a2575cba4]).
1.2 I have this setting On: Editor -> Editor Settings -> General -> Interface -> Scene Tabs -> "Restore Scenes On Load".
2. Copy/Paste .glb model with a skeleton to the project folder.
3. Double click .glb file in the editor and click Reimport.
4. Right click .glb file and select New Inherited Scene.
5. Click ctrl+s to save that scene for example player.tscn.
6. Right click player.tscn and select Instantiate.
7. Save everything and restart Godot editor. When launching editor you will see message `ERROR: Condition "skeleton->size == 0" is true. Returning: RID()` in console and Output.

### Steps to reproduce (from MRP)
