VR Arms Distortion

Hi,
I recently started trying to convert a 3rd person shooter project I created a while back to a full body VR project. I managed to take care of the camera and character’s height and now I’m stuck on the hands, which don’t follow the motion controllers correctly or are just being distorted for some reason.
I’m trying to use a FABRIK node in the ABP from the clavicle bone to the hand bone with the transform of the motion controller and it’s not working correctly.
To clarify, I created the rig for my character in ActoreCore AccuRig and exported to UE5 and all of the animations worked perfectly fine before converting to VR.
Anyone knows why this happens?
