Help! I think our fiddle leaf tree is dying 😭

Hi! My partner and I are first time plant owners. We recently bought a fiddle leaf fig from IKEA and she looked absolutely perfect when we got her. A few weeks after, leaves from the bottom started dropping. And now the leaves at the top are browning. The browning are mostly on the edge of the leaves and they feel crisp to touch. We water it when the soil is dry (we use the chopstick method).

Here’s a photo for reference. Can anyone please help? What should we do to heal her? 😭
