My Ficus lyrata has been dropping leaves like crazy, and I'm still figuring out what went wrong

My Ficus lyrata has been dropping leaves like crazy, and I'm still figuring out what went wrong. I moved it away from the window thinking it needed less direct light, but that seemed to make it worse. Now I'm wondering if it was actually a watering issue or maybe just shocked by the move itself. Has anyone else had success with fiddleleaf figs in lower light? I'm determined to save this one.
