Everything looks fine in edit mode, but distorted in object mode Disabling modifier in viewport does the thing, but I want to animate it, which isn't possible with the armature disabled (see this clip).

I look to some posts with the same issue:

...and tried this:


Select Armature > Pose Mode > Pose > Clear Transform > Location (alt G), Rotation (alt R), Scale (alt S) (nothing's working).

I downloaded the .blend file and can't reproduce the issue. Maybe disable some addons, get a clean install of Blender, etc. Here's what I did right after opening the file, everything seems fine to me, let me know if I missed something:
