Or downloading 1,245,963 trains from all 12 moons of Jupiter with no experience in basic computer ops, let alone how to repair faulty stuff or find missing KUIDs. Set content filter for faulty = true, select all delete all. Set for missing dependencies = true, select all delete all, refresh asset view and repeat until nothing faulty or missing dependencies is left. Then do an EDR. Probably simpler to delete the whole smash and resintall it, and next time take downloading new stuff in small bites.
