PlayStation Ac44 Brake Issue

My CW44AC has trouble moving. It has to be in N6+ to even move, and sometimes N8 to stay moving, I hear a lot of brakes squeaking, even though all brakes are released and cut in, I even manually checked every handbrake. When I go to N4-, my trains just slows until it stops, even going downhill, does anyone know what's happening?

 

Did you released the handbrake too? In some cases it is applied.

 

I checked every handbrake on that train

 

Does your train have DPUs and are they set up correctly?

 

I'm not sure and how do you set them up correctly
