Blender particles to UE5 (Alembic)

Workflow: Embergen → Blender → UE5.2

Created a particle system in Embergen. Exported it as an Alembic file sequence.
Imported that sequence into Blender to create a single cache file. I don’t see a way to import an Alembic sequence into Unreal.
The imported sequence looks fine in Blender when I play the animation.
So, I export it to Alembic. But when I try to import that file (as a geometry cache) into UE5 I get:
Failed to import ‘…/…/…/…/…/EmberGen/Blender_ABC/water.abc’. Failed to create asset ‘/Game/MyStuff/Water/water’.
Please see Output Log for details.

And the Output Log has ZERO additional information.

I’ve tried about 1 zillion export/import combinations but have no idea what the problem is.

Thoughts?
