Animation files not working

Godot Version
4.4.1

Hello, I am using Godot v4.x I am unable to get animations from a Mixamo FBX file to work.

When I set up an AnimationTree, my character is stuck in a T-Pose.
I have confirmed the AnimationTree is Active, the Anim Player is assigned, the AnimationPlayer Root Node is assigned to my character’s skeleton, and the Process Callback is set to Physics.
When I try to re-import the animation files, my editor seems bugged. Double-clicking the .fbx file does not show an “Open Anyway” button.
When I use the Import dock and set the preset to AnimationLibrary and click Reimport, no .animlib file is created.
I have already tried starting a fresh project and completely re-downloading and re-installing Godot. What could be causing the importer and animation system to be broken on my machine?

Are you able to select and preview the animations through the AnimationPlayer?


Or is your issue more related to importing the animations?
