Sony DSC-RX100 IV fell : won't turn on anymore

Hello guys!

I'm a bit desperate as I broke it seems, my recently acquired -less than 2 months :((((( -Sony RX100 IV.

It fell from shoulder height on the floor tiles, right on the upper right corner of the lens barrel: aperture ring is a bit deformed and won't rotate more than 45°

It was turned off when it fell, but now wouldn't turn on anymore... no power sign, not detected by the computer as well, nothing. As alive as a brick.

Any idea what needs to be replaced (aside from the lens ring) in order to bring it back to life?

Thanks in advance :)
