Thanks bot, I opened the recommended URP 2D Shaders reference project, but the character in this project is still magenta. I have already set the Example 2D URP Asset in Project Settings > Graphics > Scriptable Render Pipeline Settings and Project Settings > Quality > Rendering > Render Pipeline Asset
I received the following error:
Shader error in 'Universal Render Pipeline/2D/Spine/Skeleton': Couldn't open include file 'Packages/com.esotericsoftware.spine.spine-unity/Runtime/spine-unity/Shaders/CGIncludes/Spine-Common.cginc'. at /Unity/Projects/testURP/Library/PackageCache/com.esotericsoftware.spine.urp-shaders@b1fe837e8a/Shaders/Include/SpineCoreShaders/Spine-Common.cginc(2)
