Baking animation from sequencer messes up my mesh

Hello there,

I’m trying to make custom animations using the default UE5 mannequin. I switched to IK for the arms and everything is fine and dandy until I bake the animation sequence. It messes up my mesh. This is how the animation looks:

If I turn off the IK, it bakes alright so my assumption is that the arms IK are streching towards something, I dunno.

Would love any help I can get!
Thanks!

It seems that if I simply move the arm IK slightly up, it distorts the mesh after baking.

I tried a fresh project. The only thing I did was create a sequence where I only lift the left hand slightly up with IK.

Same problem here as well. What’s happening, lol?
