Unreal livelink going incredibly slow recently

Hello, not sure if something has changed, but for the last couple of weeks several of the animations I have tried to transfer from Iclone into unreal using the Unreal Livelink transfer feature have gotten stuck going very slow at the “sample motion bone” phase of the transfer, it basically transfers at a crazy slow rate and takes up to 3 hours to finish. At first thought it was when I had the new UE5 option selected, as for one of my characters/animations switching it back to UE4 made it go it’s normal speed (about 10 minutes to complete) but now this hasn’t worked on my latest transfer and i’m getting the super slow transfer on UE4 option aswell.

Any idea what could be causing this and how to fix it?
