How to fix invalid snapshot metadata tree/APFS snapshot error?

Snapshot is a set of history files captured at a particular time, capable of being reloaded to restore the earlier state. APFS snapshot is like several panoramas of APFS drive at different times. Thus, whenever our APFS file system goes wrong, we can go back to the previous status of disk.

If APFS snapshot is invalid or the APFS snapshot metadata tree is invalid on macOS, the status of partial data stored on the APFS drive can be affected. It means the snapshot of some files have already been damaged or missingAnd the APFS drive might not be mounted for file accessing as usual. Under this circumstance, we are not allowed to access the APFS drive and files saved on the drive are lost.

Here is a case from forums:

Since I converted my internal hard drive to APFS file system, it worked perfectly. But when I tried to store some files in the drive today, I failed to mount it. Then I checked the drive in Disk Utility, I got an error message saying: "APFS snapshot is invalid". I have no idea what happened. Anyone can help me to fix/repair invalid APFS snapshot error?
