WHY DOESN'T ANY "CORPSE AFTER DEATH" SCRIPT WORK!?

TL; DR, for the past hour I've tried like 10 toolbox scripts, checked the Roblox forums, and even asked the Roblox robot, but no luck. Nothing just works for some reason. Last time I tried, a ragdoll spawned (standing upright...) but my camera began switching between the ragdoll and my actual character.
