The APFS Volume Locked by Mac, How to Recover Data?


Summary:

I have trouble accessing data with an encrypted APFS volume on mac 10.13 High Sierra. It refused to open with all passwords, and neither could I find it in Disk Utility. The error was: Error unlocking APFS Volume: Couldn't mount disk (-69842). Is there any idea to fix this issue?
 
After upgrading to macOS Mojave 10.14‎/High Sierra 10.13, our Mac internal hard drive will not only be formatted to be APFS, but also will be automatically encrypted. Sometimes, there are errors happen to our APFS drive and make it can't be unlocked even with the right password. At that time, it can't be mounted, unmounted, or even ejected, and also cause the Disk Utility to freeze whenever connected. When plugged, it asks for the "'Error unlocking APFS Volume: The given APFS Volume is not locked (-69589)'" one time. If it is correct, it asks for a second time, but disk does not mount after that message box disappear.
 
Unlocking APFS volume error can be caused by file system error, damaged or corrupted drive, etc. Regardless of the causes, the important data stores on the disk become inaccessible. The problem is, how can I get them back?
