I had a similar problem that "went away" with a bearing flush and lube. Mine would jam, (at the worst possible moments) then release if I released tension on the halyard. Am interested in what you learn/solve, I'm not confident I really understood the issue or solved anything. A halyard restrainer was recommended by Harken (without seeing the boat) but it wasn't needed. What I have done is move the headsail up slightly by adding shackles at the tack, (a protoype tack pennant) this to improve the sheet lead, but it seems a good way to "prove" the usefulness of the halyard restrainer without investing.

Drop the sail and flush both the swivel and the drum. Flush liberally with water from multiple angles. Spray some McLube in both if you like. It's optional but a good idea. While the sail is down, inspect, as best you can, all the joints in the extrusion, if anything looks amiss, investigate it further. Next, from off the boat, sight the furling line where it enters/exits the drum. It should be very close to perpendicular. If necessary, reposition the forwardmost furling line block to achieve perpendicular. The furling line should move up and down as it feeds on the drum. If it coils in the top, move the block down. If it coils low, move the block up. As a last check, have a friend furl and unfurl the sail while you observe the swivel and halyard from a distance with binoculars. Do you have a halyard restrainer?
