Question Animation Rigging shifts the player down

Hi all! I am using the Animation Rigging package to make the character look where the camera is looking. However, as soon as I enable the "Rig Builder" component on my player, the whole player just shifts down a little, and his feet go below ground. I tried setting the "weight" of the rig to 0, but the player is still below ground. As soon as I disable the "Rig Builder" component, the player is shifted up to normal.

What is the bug here, and how to fix it?
