As of 11/4/22, with Patch 1.02, this achievement is finally obtainable on BOTH console and PC, and the game thusly may be 100% completed on both platforms.
Pro Tip to make this a lot easier: play on the easiest difficulty and use the Untouchable perk, which you obtain by getting an S Rank, getting 10 Gold Teeth, and completing the three challenges for Stage 19. This allows you to tank most hits throughout the game and keep your combo going. The only thing that can break your combo are power attacks from bigger thugs if they grab you and punch you to the floor, or if an explosion knocks you to the ground as well. Using the perk gives you a 250,000 point penalty, but if you keep your combo going high enough, that won't matter because you'll easily rack up over a million points on most levels.
Also, if you previously got S Ranks on all missions before the update and the achievement hadn't popped, here is a solution from RoninSouly in the comments:
I finished all levels on S but it glitched back then. after this patch I finished the last level > quit the game > re-launched and finished the Factory level and it popped.
