Mystery error - fatal error reading snapshot

Thread needs solution

I'm getting this mesage:

A fatal error occurred while reading the snapshot.  The snapshot was canceled by the system.  See system logs for details.  Check for a solution.

And I have no idea where to start.  "Check for a solution" is a link that leads to an acronis page that says no information.  I've looked where I think the log files are but I can't ferret out anything interesting.  

Any ideas appreciated.

Windows 10 build 19041

Acronis True Image 2020 build 25700

I've just reactivated backups after several months' hiatus, by adding more disk space for it.  I expect there's probably something about this that acronis doesn't like, but I don't know.

Thanks, ==mwh

Please download a copy of the Acronis VSS Doctor tool and run this as Administrator on your PC to see what issues it detects related to snapshot areas (VSS is used for snapshots).  Let the tool fix any issues it offers to fix for you.

If needed, consider running CHKDSK /F against all the drives involved in your backup tasks as disk or file system errors can cause these type of error messages too.

Not a complete solution by itself, but ultimately led to finding an obscure (& very difficult to resolve) VSS error in Windows - something that probably came from disk cloning, had no effect on system operation, but caused a problem in Acronis.
