Character weird deformation in Unreal

Hi all
I made some animations for my character in Blender 2.8. However one of my animation have some weird deformations in Unreal. I imported as FBX with recommended settings. I tried also various different settings with no luck. The other two animation I have made are fine.
Any ideas?
Thanks in advance!
