Yes. We don't know for now where is problem in exhaust. Or closed turbo, or clogged SCR (DPF)
Connect back EGR pipe or what you disconnected and open exhaust right after aftertreatment injector. If engine will run the problem not in turbo. Another quick test is have someone to turn ignition on while you staying by the turbo and listening. Is it make some sound like parts chaffing. If so the actuator is moving.
