How to fix/repair invalid APFS snapshot error?

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?
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 on macOS, the status of partial data stored on the APFS drive can be affected and the APFS drive might not be mounted as usual. Under this circumstance, we are not allowed to access the APFS drive and files saved on the drive are lost.
