Once loaded, the crossbow is not positioned in the center of the screen. In previous updates this issue would reappear, but from what I’ve seen, would occasionally get hot fixed and be reset back to its normal position.

The image to the right displays a loaded crossbow as of 1.17.41

The image to left displays what it should normally appear as. (This image originates from Java, but in past bedrock versions it would be identical to this.)
