Character disappears when selecting AnimationTree node

Godot Version

4.5

Question

How can I see the character when using the AnimationTree?

Animated a Skeleton2D using the AnimationPlayer node. Works fine.

When selecting the AnimationTree, the Polygons disappear.

Adding an Idle Animation doesn’t resolve the issue. I can still see the pivot points from the various body parts, but they don’t move either.

The Animations only change rotation and position of bones.
