Growth in Neofinetia possibly infected?

[Shoreguy]

No idea what caused the problem.

The issue is what to do now.
I would unpot the plant, discard the medium it is in.
Snap off the dying growth being careful not to damage the live remaining roots. Also remove any dead roots if possible without disturbing the live ones.

Finally and everyone here knows I am not a fan of sphagnum although useful here, wrap some strands around the base and lightly spray the base every two days especially if it will be getting some natural sunlight, three days for artificial. Do not overdo the natural sunlight which could stress the plant. If any new rooting is seen up it to two days.
Pot it in Spring to the method of your choice. I have stopped giving recommendations on that do to unfair criticism.

Finally, 45F is excessively cold. I am aware of wild conditions but are you intentionally subjecting it to that in a weakened condition?

Thanks for the recommendations. I'll snap off the dying growth and wrap the roots in some sphagnum moss like you mentioned. I'll be careful not to have direct sunlight on it.

As for 45F, I kept it a couple of days indoors but with the window open for a couple of days thinking that would be more similar to its previous environment but I will now keep it in my bedroom at night where it reaches 60F at the lowest.

Some direct sunlight through a bug screen or light curtain would be helpful. Just be careful the sphag is lightly moist at the start.

Place it on a small dinner plate, not on anything that the roots would stick to like terracotta.
