Bones randomly rotating during imported animation

Hello everyone

I animated a character in Blender and imported several animations to Unreal. For some reason, two of the animations seem broken/distorted. I have no idea what the reason could be, they work perfectly fine in Blender, as do all the other animations. It’s just these two specific ones.

I don’t believe the problem lies with Blender, my export settings are exactly as recommended by all the forum posts, youtube videos, etc. I’ve seen about it lol

(and as mentioned, the other animations work)

Here is the animation. The character is supposed to just lift his arm up and hold the staff high. Instead the hand/palm bone completely rotates a few times in like 4-5 frames.

I’d really appreciate any help!
