Blender to UE5 FBX Animations without Bones

Hello,

In Blender, I made animations of objects without bones. I export and import without problem in UE 4.27. When I open the same project in UE5, animations was freezes ! I don’t succed to import them again, I got an animation asset, but animation don’t move !

I reinstall UE4.27 and I confirm that it’s working with this version but not with UE5 !

Do you know how it’s possible ? And how to fix it ?
Do you have a particular settings of export from blender and import in UE5 ?

Thanks a lot for your help
