As the latest file system of apple, APFS is still not immune to unexpected crash. Even a volume/disk formatted with APFS, you will find it crashed/dead/failed sometimes. What's worse is that the APFS system volume fails for any unknown reason. As a result, your Mac won't boot at all and you are unable to get access to all data on the computer.

In fact, that happens quite often after an unsuccessful system update or system crash. The Mac system provides a system recovery option, while such an operation may write over the original data and permanently destroy it. So before repairing the system, it's reasonable to recover important files back.

This passage will give you step-by-step guidance on how to recover data from failed/damaged/dead/crashed APFS system volume. Here is a video tutorial to recover data from failed iMac hard drive:
