Can't see any spacers or adjustable preload from the pictures. Here is the essence. You can't ride it how it is. Tear it down and take a picture of all the parts to see what you have and any opportunity to remove some of the spacing between the adapters and the crank. If not, you need to go to another solution but will withhold that until you pull it apart and take a picture of all the parts. By definition there should either be a wave washer or mechanical preload adjustable ring. I can't see either in the pics but that maybe because of the tightness. It has to come apart anyway and so tear it down and take a picture.
