My Hackintosh lost power and crashed a few days ago, and now I can’t boot into macOS.

Initially I noticed the OpenCore boot sequence was missing from the BIOS, which I have since fixed. Now when I boot I hit the OpenCore boot loader where I choose macOS, and I reach the macOS FileVault login screen - I enter my password and the system spends about 30 seconds trying to load before a black screen with a icon appears. According to Apple this means the copy of macOS on my disk is ”not a copy my Mac can use”?

As per that support article I booted into macOS recovery to repair my disk, but Disk Utility and Terminal can’t see my internal disk. So I booted into OpenShell and this is what I see:

Code:
map -v

Ctrl[2F5] APFS [Update]

If I’m understanding this output correctly, it seems my APFS partition has not been mapped as an accessible file system (FSx) which explains why macOS can’t boot to it? Have I understood that correctly? Either way, can somebody point me in the right direction for fixing this please?
