Mac OS disappeared (bootcamp)

Hello everyone, i have installed windows using bootcamp and have been using both OS. Today suddenly the Mac OS has disappeared from boot options. I used command+R to boot in recovery but it took me directly to internet recovery.

In time machine backup, it just says searching for time machine backups but no backups appear.

In the disk utility, i can see my mac partition but I don’t know how to proceed further. I am attaching an image. (disk0s2 is mac partition)

Please help as I don’t want to lose my data.
