Stucked when import alembic to UE5, really confused

Hi :smiling_face_with_three_hearts: :smiling_face_with_three_hearts:, I create a abc file from Blender and want to import to UE. However, I stucked on this scene when I click import.


I guess it’s because I mess up with some settings or maybe it needs bluprints? Which setting shoud I adjust when I export and Import it?
Thanks a lot!! :kissing_heart: :kissing_heart:
PS: here is the original blender file
Sprout.blend (7.8 MB)
