No animation anymore when I Package the project ! BP character

Hi !
I do a scene with the sequencer on Unreal 5.2.
Main character is “Detective character 2” on the market place witch have got a UE5 skeletal Mesh.

When I launch the sequencer or render, everything is find, character goes where it have to.
When I package the projet, start the scene by the sequencer ingame, the character is not animated anymore. The skeletal mesh just follow all the transform point in T pose. (All other characters on the scene works well)
But this one is integrate on a BluePrint (I try animation BP or Custom Mod, but nothing change)

What could do such a thing ?

I find out !
In the sequencer, click on BluePrint and add a Track “Skeletal Mesh”
instead of animate the BP, we have to animate the skeletalMesh Itself.
And then, it works in the UE5 and also in the Pakage project.
