As you can see in the attached video file, when I crop files in preview mode, if I drag the crop from the left side of the photo, I cannot reframe and rotate because the crop is reseting. This happens only when drag the crop from the left side of the photo in preview mode. If I drag the crop from the right side of the photo everything works fine. This happen in PM6 Build 4484
Thanks for the video. I am unable to reproduce on my system. Unfortunately, I could not see your settings (you have that panel hidden) so maybe there is something that I'm missing on my end.
