Cant create groom binding

Hello dear community,

I imported an alembic groom asset into ue4 from blender. I tried to create a groom binding asset with right click, but it doesnt create one. The Process stays at 0%. I leaved it for an hour, no change happend. My CPU is nearly 100%.

I have an AMD Ryzen 5 2600.

I dont know why it cant create a binding asset, the import of the alembic file worked.

I hope anybody can help me.

Thanks for your help
