Monstera Cold Damage

My monstera of 6 years was left out in the cold over Thanksgiving with below freezing temperatures. I fear I pushed the envelope too far this time and my baby is dying. All of its leaves are browning and many of the stalks have wilted. It’s lived mostly a good life and had been watered regularly, but having been left in the first New England below freezing temps might have just put the nail in the coffin. It’s been outside getting plenty of sunlight, and in the process of warming up at our sliding door.

Does anyone have experience in bringing something like this back to health or is it a lost cause?
