Can't get ragdoll

I’m fully folowing this tutorial (Ragdoll 101- Part 1 The initial setup and keeping the Collision Capsule attached - YouTube), but I can’t get ragdoll like in video. It’s clear new project, I’v tried both “Set Simulate Physics” and “Set All Bodies Below Simulate Physics” but nothing happening. Character just continue playing idle animaton, running etc
What I’m doing wrong?
