Money tree problems

I bought a money tree about a year ago. This is my very first plant and I am trying to take care of it. In the spring/summer it grew into a very healthy and beautiful plant. It wasn’t until the fall where things started to become difficult and problematic. Around November/december the weather in my area got considerably cooler and my leaves started falling. In the past 2 months a majority of the big leaves fell and within the past couple of weeks all the leaves started to turn yellow. I am getting a little discouraged to see that all the work that I did to keep the plant healthy was gone in a short period of time. I and want to to know if there is a way to salvage this plant and make it bushy again and if there any thoughts on whether or not my plant is in a good or bad shape.

For context, I regularly watered my plant and add liquid fertilizer. I stopped watering it for about a week (over a month fertilizing) since I was informed that I overwatered the plant in the winter but that has caused many leaves to turn yellow. The soil is still damp so I am hesitant to add more water. Additionallly, my plant is propped right beside the window of my apartment. Unfortunately the windows and my plant are directly under 2 powerful vents. I get a lot of sun at the beginning of the day/mid morning and the windows face the north. I drain excess water when watering my plant and I have a humidifier to ensure that it is misty.

I provided 5 photos of the plant from 4/2024, 9/2024, 11/2024, 2/2025 and today. I really need assistance on what I should do. Is pruning necessary and will it get bushy again. Any comments or constructive criticism is welcome.
