Looks a bit beyond me. I have a handful of answers but there are clearly numerous clashes and thus the solver's mainstay - letters given by crossing words - is undermined. Would need to cold solve plenty of clues which remain baffling.
Ironic that a clash would have helped with Azed 2351. I posted a year or so ago about a printer's devilry clue which somehow failed to win approval (a very similar clue won), and was advised that maybe I'd posted too late. I pooh-poohed the idea, but noticed Azed gave a stern warning soon after about people posting too late !
This time I made sure I posted Friday afternoon, but my downfall was not checking my answers thoroughly. I note that the first clue I solved, 11A, (Some sort of old weapon king sheathed, not required) was SPARKE, but I blithely entered SPARRE and thought no more of it. (I knew it meant spar but the conviction that it also meant spear slipped in under my guard).
Such a shame! I toiled with RHAGADES but I knew 'cracks in the skin, extremely rough, aching around edges' wasn't great. Then I tried googling 'rhagades', and came up with a clue that was light years better.
Could be caused by syphilis, which also produced 'sabre shins'. Was treated with silver nitrate. Suddenly I had a clue which stood a real chance.
Nasty business, _____________: might display sabre shins, silver used for treatment?
Comp anag & lit (business rhagades/sabre shins Ag used). I'd created a clue far closer to perfection than most I've managed, but it was academic as I'd got an answer wrong.
If only that R/K hadn't been the one unchecked letter in 11A! A clash would have alerted me to my folly. (No good exhorting me to check answers more thoroughly - I do try, but I fear this one would still have slipped through).
