Did you activate “UV write” in the alembic export options in Maya ?
Maybe the bake texture ROP is the way to go, but I never had luck with it
I'm happy I'm not alone, I experiment a crash in Maya playing Alembic files almost every time I import them. I don't think there is anything wrong in your rop alembic, it's a Maya issue. In my case I think it's related to the GPU playing the animation, because if I render the scene it renders ok , it's when I play in the viewport that it crashes. So the only workaround I found is to visualize the alembic geo in Maya as bounding box and not full geometry
