Have had my fiddle leaf fig since January. It started to look a bit sad and then the pot it was in smashed. I repotted the plant two days later (see top row of photos, in the middle). It then started to lose most of its leaves day by day and as of yesterday we’re down to one leaf but it’s very green. Is it dead or can it be fixed? Have been keeping it in indirect light and the soil is moist. Osmocote was also put in the soil when I repotted.

This will want direct light at this time. Most likely the lak of light is causing leaf loss. For me, it would be a bit early to apply fertilizers. I don't think that it will hurt the tree, but it won't be taking up much during recovery.
The first thing that I would do would be to put it in direct light. Make sure the soil is moist but not very wet. Only water after the top is almost completely dry. This will keep any infections from starting. Then apply some dolomitic lime. This will correct any pH issues that it may be having.
If your household is using a water softener, then you will not want to use this water. The salt content is way to high. Purified, or bottled water is fine.
It is still alive for now, but without proper lighting it will attempt to go into a dormant state.
