Particles exported as Alembic from Blender are no longer read as vertices when reimported.

Hi everyone, I have a question that I can’t find a solution to and it’s been on my mind for a while now.

With the latest version of blender (4.2.6 LTS) I can no longer export a particle simulation in alembic and reimport it as vertices. In fact, it reimports it as an empty animation.
What’s changed?
Does anyone have any ideas?
Many thanks in advance.
