When pressing the option during startup, MacOS isn’t shown as an option to boot into.
Using the tray in win10 to “Restart in MacOS” also doesn’t work. It just restarts back into Windows 10.
It is an iMac 27" 5K 2017 model, running macOS 12.1. And in the windows side, it is running Windows 10 Pro Version 21H2.

Below is output showing the internal drives after running diskutil list

I followed the steps posted. It seems it was disk1 this time so I used disk1 in when executing the commands.
Reinstalling also doesn’t show the mac drive (about 800gb), so I am currently unable to reinstall as well.
This is the disk utility showing the drives. Below shows what I believe to be the macOS drive, which is currently unmounted so I am unable to boot into macOS or even select the drive for reinstalling macOS.
And here below is the startup disk selection.
