APFS Partitions corrupted
Your best option is to use any recovery tools possible to mount the Volumes and get the files off the disk. If macOS Recovery can access it, then go to Disk Utility and simply make a disk image or something so that you have all your files. Then, remove the APFS Container Disk, and erase Apple SSD AP0512J... making sure that there is nothing left. Then, reinstall macOS from the reinstall macOS option in Recovery. This will allow your Mac to boot normally and you can later restore the files that you were able to previously recover.
