Nope
the nose cone is not attached to the rotor and does not spin.
The glow is from the exposed front bearing which now is in a bad state due to a significant imbalance in the fan rotor
the engine is no longer running but is freewheeling (with a bad bearing) from the pinwheel effect of the air coming in.
The engine will continue to freewheel spin like a car running on a flat tire, until the plane stops on the runway. Not a big deal except for the noise in the cabin.
