Alembic Geo Cache Crashing in Sequencer

Hi there, I’m getting an issue with repeated crashes of UE whilst playing Alembic Geo Caches in the sequencer.

The crash seems to happen at random whilst playing or scrubbing. If I copy/paste/duplicate any Alembics in the sequencer it crashes immediately.

The Alembics in Question are all below 150mb and consist of a static point number - the animation is their movement.
They are also spawned in and out of the scene before and after the loop finishes.

using stat MemoryPlatform doesn’t show any particular spikes or high values in particular.

Wondering if this is a common issue with Alembic Geo Caches as it’s still in the experimental stage?
