Losing leaves on fiddle leaf fig

My fiddle leaf fig has lost all but one leaf. And I think it’s going to lose this last one too. It’s gone through cycles of losing leaves before, but it’s never lost all of them. And it has always eventually grown more leaves back than it lost. Pictures are of this last leaf left - this is what the leaves look like before losing them. Can anyone tell me what the issue is? And if I can fix I it, how? #FiddleLeafFig
