Unreal Engine struggling to import FBX character with 1500 frames of animation

Hi guys,

I’m struggling with an importing issue.
I am trying to import an FBX which I’ve mapped Xsens motion capture data to through Blender. The cumulative frames equal 1500. I get stuck when trying to import this FBX into UE5 and I just get stuck at a loading screen for ages which never completes (Displayed in attachment).

Any help would be much appreciated. Thanks.
