disk0s2 unknown format - cant boot into MacOS

Hi,

On my mid 2012 MBA, in which I already have a bootcamp partion for windows, I tried to resize my main Mac partition and add another one (~23gb) to trial ubuntu on.

After the resizing was complete my Mac was restarted and on boot, the only bootable drive that showed was "Windows" which does not work. MacintoshHD is missing.

I restarted again and pressed Option-Command-R to start up from macOS Recovery over the Internet and tried to investigate whats gone wrong and it seems like my Mac HD (~107GB) is now unrecognised (purely labelled as "disk0s2") and not moutable.

Is there anyway I can get my data of that of this drive? or Mount it? See pictures below and please let me know if you need additional information.
