Problem statement

I am trying to use exported Spine files in Godot, but the runtime reports texture loading errors and Godot crashes when configuring SpineSkeletonDataResource.

What I have tried:

I exported my Spine project using binary format.
The exported files are:
- starspine.skel
- starspine.atlas
- starspine.png
I placed all three files in the same Godot project folder.
Godot can recognize/import these files.
I checked my Spine project and made sure there are no Chinese characters in bone names, slot names, attachment names, constraints, animations, skins, or events.
The first line of my atlas file is:

starspine.png

The PNG file is in the same directory as the .atlas and .skel files.

What I expected:

I expected the atlas texture to load correctly and the SpineSkeletonDataResource to be configured normally with both the .skel and .atlas files.

What actually happened:

After placing the three files into the Godot project, the files can be recognized, but Godot outputs three texture loading errors. Then, when I configure SpineSkeletonDataResource, as soon as I assign both the .atlas and .skel files, the Godot editor crashes immediately.

Steps to reproduce:

Use Godot 4.5.1.
Use Spine Editor 4.2.11.
Export the Spine project as binary:
- starspine.skel
- starspine.atlas
- starspine.png
Put all three files into the same folder in the Godot project.
Create or configure a SpineSkeletonDataResource.
Assign the .atlas file and the .skel file.
Godot crashes immediately.

Runtime information

Godot version: 4.5.1
Spine Editor version: 4.2.11
Export format: Binary .skel
Spine Godot runtime: spine-godot GDExtension for Spine 4.2 / Godot 4.x

ERROR: Failed loading resource: res://starss/images/animation_sprite/spine/starspine.png.
ERROR: Error loading resource: 'res:///starss/images/animation_sprite/spine/starspine.png'.
ERROR: spine_godot\SpineAtlasResource.cpp:157 - Can't load texture: "res:///starss/images/animation_sprite/spine/starspine.png"

I can provide the exported .skel, .atlas, and .png files if needed.
