after years of stopping it is normal that a tape deck does not work, belts melted into the pulley, maybe even the idler works badly due to many years of stop.
It is not a complicated job, a change of belts always works out; at that point it is also better to carry out calibrations to bring the deck back to the manufacturer's specs
