Export GLB animation blender 2.8

Somebody knows why when I export an animation for glb in blender 2.8, the model does not appear in the gltf viewer, and when I stop the animation if it appears but in the windows 3d viewer if it appears without any problem … ??? Here I leave the images

Please always share blend and glb files when posting such questions. In most cases, working with your files is the only way to provide help.
