The Issue is solved!
Its a new “Bad interaction” between autodesk maya group names and UE5.
If your object center is not where your root bone is, UE now detects the group where you put your bones as an actual bone in your object.
Just click settings then show all bones.
Then right click what was supposed to be your group name… and add a body to it!
And done.
Why is my group name a bone now?
no clue!
should it be a bone?
nope!
But the issue is fixed.
